Alterations in Retinal Vascularity in Severe Psoriasis.

PURPOSE: To evaluate the changes in retinal vascularity in patients with severe psoriasis. MATERIALS AND METHODS: Patients with severe psoriasis [psoriasis area-severity index (PASI) >10] who did not get any systemic treatment in the last year and do not have any ocular diseases were included. All patients underwent detailed ophthalmological examination, including optical coherence tomography (OCT) and OCT angiography (OCTA). Vessel densities (VD) of Superficial (SCP) and deep (DCP) capillary plexus, foveal avascular zone (FAZ) diameter, central retinal thickness (CRT) were analyzed and compared with age-sex matched healthy adults. RESULTS: Fifty-three patients (13 F, 40 M) and 56 controls (16 F, 40 M) were included in the study. VD of SCP (50.4%±3.9 vs. 51.4%±3.2) and DCP (52.6%±6.4 vs. 55.4%±5.7) were lower in psoriasis group compared to controls (p < .05). Presence of psoriatic arthritis was related with an increased CRT (p = .000), larger FAZ and decreased foveal VD in SCP (p = .01, p = .02, respectively). CONCLUSION: Severe psoriasis causes a decrease in retinal blood flow and presence of psoriatic arthritis is related with decreased foveal VD.

The Impact of COVID-19 Infection on Macular Capillary Perfusion.

Objectives: Thromboembolic complications related to the COVID-19 infection are frequently reported. This study aims to evaluate the impact of a prior non-severe COVID-19 infection on retinal microcirculation with optical coherence tomography angiography (OCTA). Methods: A total of 83 eyes of 43 patients with a history of non-severe COVID-19 infection confirmed with a positive PCR test (Group 1) and 30 healthy controls (Group 2) underwent detailed eye examination, including optic coherence tomography angiography (OCTA, RTVue-XR Avanti) scanning. Vessel densities (VD) in the superficial capillary plexus (SCP), deep capillary plexus (DCP), and foveal avascular zone were evaluated. Results: The mean duration between the COVID-19 positive PCR test and ocular examination was 144.6±82.2 days. VD of SCP and DCP in the foveal and perifoveal regions were significantly lower in Group 1 compared to Group 2 (p<0.05). Conclusion: A non-severe COVID-19 infection may cause a decrease in the VD of retinal SCP and DCP.

Efficacy of Pegylated Interferon Alpha-2a in Uveitic Macular Edema Refractory to Biologic Agents.

PURPOSE: To report the efficacy of pegylated interferon alpha-2a (Roferon, Hoffmann-La Roche brands, Switzerland) in uveitic macular edema refractory to biologic agents. METHODS: Herein, we present two cases of non-infectious uveitis with cystoid macular edema (CME) who were unresponsive to immunosuppressant treatment, and whose uveitis and macular edema recurrences were prevented with subcutaneous injections of pegylated interferon α-2a. RESULTS: Two young males (27- and 30-year-old) diagnosed with non-infectious uveitis and CME were on immunosuppressive treatment. Although both received systemic steroids and biologic agents, macular edema persists. After initiation of pegylated interferon alpha-2a (Pegasys, Genentech, USA) CME regressed significantly and did not occur during their follow-ups of 14 and 12 months. CONCLUSION: Pegylated interferon-alpha-2a can be used as an effective alternative to interferon alpha-2a in uveitic macular edema cases, resistant to other immunosuppressive agents.

Effect of Cycloplegia on Anterior Segment Structures and Scleral Thickness in Emmetropic Eyes.

Purpose: To evaluate the effects of topical cyclopentolate hydrochloride-induced cycloplegia on anterior segment biomechanics in emmetropic eyes using anterior segment-optical coherence tomography (AS-OCT). Methods: Twenty-five emmetropic eyes of 25 volunteers were included. All underwent central corneal thickness (CCT) and anterior chamber depth (ACD) measurements. Anterior scleral thickness (AST) was measured at the level of the scleral spur (SS)(AST-0), 1,000 µm posterior of the SS (AST-1), and 2,000 µm posterior of the SS (AST-2) in the nasal and temporal quadrants using AS-OCT. All measurements were repeated after cycloplegia. Results: The mean age was 30.6 ± 12.4 (8-45) years. The mean CCT did not significantly change after cycloplegia (P = 0.7). The mean ACD was significantly increased [3.3 ± 0.2 (2.7-3.9) to 3.7 ± 0.3 (3-4.2) µm; P = 0.001]. In the nasal quadrant, the mean AST-1 and AST-2 were 512.3 ± 34.4 (433-570) and 529.6 ± 34.2 (449-599); decreased to 478 ± 26.8 (423-530) and 486.2 ± 28.3 (422-544) µm, respectively, after cycloplegia (P = 0.00; P = 0.00). In the temporal quadrant, the mean AST-1 and AST-2 were 522.5 ± 24.7 (473-578) and 527.2 ± 39.9 (450-604); decreased to 481.1 ± 33.7 (421-550) and 484.6 ± 26.6 (433-528) µm, respectively (P = 0.00; P = 0.00). There was no significant difference in AST-0 after cycloplegia in both quadrants [from 697.5 ± 46 (605-785) to 709.5 ± 64.7 (565-785) for nasal and from 718.4 ± 40.1 (632-796) to 722.9 ± 60.6 (596-838) for temporal; P = 0.2; P = 0.3, respectively]. Conclusion: After cycloplegia, there was a significant thinning of ASTs posterior to SS and a slight increase in AST in the SS level. ACD deepened after cycloplegia, and there was no significant change in CCT. Cycloplegic agents temporarily inhibit ciliary muscle contraction and may affect anterior segment parameters and sclera. Inhibition of forward-inward movement of the ciliary body by cycloplegia affects ASTs and ACD by causing a change in the mechanical force of the ciliary muscle on the sclera.

Retinal detachment in a child with Frank-ter Haar syndrome.

BACKGROUND: To present a rare case of ocular involvement in a child with Frank-ter Haar syndrome (FTHS) presenting retinal detachment. MATERIALS AND METHODS: Detailed ophthalmological evaluation including examination under general anesthesia, ocular ultrasound, and visual evoked potential testing was completed. Photographic documentation of the physical findings was obtained. RESULTS: A 3-year-old female patient with FTHS was referred to evaluate for possible ophthalmic involvement. The patient presented with the classical dysmorphic abnormalities of the syndrome. Ophthalmologic evaluation revealed a high, against-the-rule corneal astigmatism in the right eye. In the left eye, the red reflex was absent with a suspicious membrane behind the lens, and a sensory exotropia was present. Ultrasonography confirmed retinal detachment with no history of previous trauma. Due to poor visual evoked potentials, no surgery was planned. Astigmatic refractive error was corrected with routine follow-up. CONCLUSIONS: FTHS is associated with multiple ocular involvement such as megalocornea, congenital glaucoma, or colobomas. This case report is the first to describe a high, against-the-rule astigmatism and retinal detachment in a female child with FTHS and demonstrates that an early and detailed ophthalmological examination is essential for these patients.

Prevalence of Polypoidal Choroidal Vasculopathy in Eyes with Neovascular Age-Related Macular Degeneration Resistant to Intravitreal Anti-VEGF Treatment.

Objectives: To determine the prevalence of polypoidal choroidal vasculopathy (PCV) in intravitreal (IV) anti-vascular endothelial growth factor (anti-VEGF)-resistant neovascular age-related macular degeneration (nvAMD) cases. Materials and Methods: Eyes that were diagnosed as having active and treatment-naive nvAMD in the Ege University Ophthalmology Department, Retina Unit in 2011-2018, were non-responsive to IV anti-VEGF treatment, and for which indocyanine angiography (ICGA) could be obtained were included in the study. Active nvAMD was defined as the presence of fresh hemorrhage on clinical examination or findings of subretinal, intraretinal, or sub-retinal pigment epithelial fluid on spectral domain optical coherence tomography and accompanying fluorescein dye leakage in fluorescein angiography. Eyes that had activation findings despite at least 6 consecutive intravitreal anti-VEGF injections were defined as non-responders and underwent ICGA to assess for PCV. The diagnosis of PCV was based on the Everest II study criterion. Results: A total of 97 eyes of 88 patients were included in the study. Of 88 patients, 44 (50%) were female, 44 (50%) were male, and the mean age was 75.9±8.3 years (range: 59-93). The mean number of anti-VEGF injections until the time of ICGA was 7.3±2.2 (range: 6-15). PCV was detected in 62 eyes (63.9%) on ICGA. Conclusion: The prevalence of PCV is quite high among eyes with IV anti-VEGF treatment-resistant nvAMD in Turkey (63.9%). ICGA evaluation for PCV should be conducted for all nvAMD cases that are non-responsive to IV anti-VEGF treatment, both to shed light on the reason for resistance and to modify treatment as necessary.

Sheath-Preserving Complete Optic Nerve Avulsion Following Closed-Globe Injury: A Case Report.

A 29-year-old man presented with a sudden loss of vision after a closed-globe injury. At presentation, he had no light perception in the right eye and the right pupil was dilated and nonreactive to light. On ophthalmological examination, the area of the optic nerve head was excavated, suggesting optic nerve avulsion. Magnetic resonance imaging scan showed optic nerve avulsion without rupture of the optic nerve sheath. Four months after the injury, the patient's visual acuity remained unchanged. Gliosis developed at the avulsion site. Closed-globe injuries may cause severe posterior injury even if there is no anterior damage in the eye. To prevent unnecessary treatment, trauma patients should be examined carefully appropriate imaging to confirm the diagnosis.

Impact of COVID-19-Related Lockdown on Glaucoma Patients

Objectives: To analyze emergency and outpatient admissions by glaucoma patients during complete lockdown due to coronavirus disease 2019 (COVID-19) to assess the effect of pandemic-related complete lockdown on glaucoma patients. Materials and Methods: This retrospective chart review included all glaucoma patients who were either examined and/or underwent emergency surgery between March 11, 2020 and May 31, 2020, a period of complete COVID-19-related lockdown in Turkey. The data were compared with data from patients seen during the same time period in 2019. Visual acuity and intraocular pressure data from patients examined after the lifting of the lockdown were also evaluated. Results: According to Turkish Ministry of Health guidelines, only emergency examinations and surgeries could be performed during the 82 days of the COVID-19 lockdown. During this period, a total of 11 eyes of 10 patients were operated and 123 patients were examined in the outpatient clinic. During the same period in 2019, 122 surgeries were performed, 39 of which were emergencies. In the first 4 weeks after the lockdown ended, 163 patients were examined at the outpatient clinic and marked visual loss was detected in 10 eyes of 9 (5.5%) patients who did not attend follow-up visits due to the pandemic. Conclusion: During the lockdown, emergency surgeries related to glaucoma decreased by 71.7% and marked visual loss was detected in 5.5% of the patients examined after the lockdown. These findings suggest that some patients were unable to present to clinics despite needing emergency care.

Impact of prolonged face mask wearing on tear break-up time and dry eye symptoms in health care professionals.

PURPOSE: To evaluate the impact of prolonged surgical face mask wearing on dry eye symptoms and tear film break-up time (T-BUT) in health care professionals. MATERIALS AND METHODS: A total of 33 health care professionals were included in the present cross sectional prospective study. In addition to a complete ophthalmological examination T-BUT measurements were performed twice for all participants in the morning (8 am) and in the afternoon (5 pm). The subjects also filled-in the ocular surface disease index (OSDI) questionnaire twice, before and after wearing the face mask, on the same day. RESULTS: Sixty-six eyes of 33 participants (17 female and 16 male) were evaluated. The mean age was 33.6 ± 7.55 (24-48) years and mean total duration with mask on between the two evaluations was 514 ± 12.5 (495-526) minutes. The mean T-BUT was 9.3 ± 1.0 (3-16) seconds at 8 am and 8.3 ± 1.5 (3-14) seconds at 5 pm (p = 0.01). The mean OSDI score was 20.1 ± 8.3 (0-68.75) at 8 am and 27.4 ± 10.4 (0-81.25) at 5 pm (p < 0.01). CONCLUSION: Use of a surgical mask for the entire work-day was seen to worsen T-BUT and increase dry eye symptoms in healthy individuals. Ophthalmologists should be aware of the possibility of worsening of dry eye symptoms with the prolonged use of surgical face masks and consider modifications if necessary.

Iris Juvenile Xanthogranuloma Presenting with Hypopyon.

PURPOSE: To report a case an iris juvenile xanthogranuloma presenting with hypopyon. CASE REPORT: A 45-day-old infant was referred to our clinic for unilateral hypopyon. Slit-lamp examination revealed a 2 mm hypopyon in the left eye while visible areas of the iris were normal. Fundus examination was normal. Topical corticosteroids and antibiotics were initiated. The hypopyon regressed to 0.5 mm after 2 weeks of treatment. The now visible peripheral iris revealed an inferotemporal yellow-brown iris mass. Clinical findings were consistent with juvenile xanthogranuloma of the iris. The patient was referred to the pediatrics department which revealed no systemic involvement. Two months after total regression of hypopyon, the baby presented with a 3 mm spontaneous hyphema causing 50 mmHg intraocular pressure. The patient was followed with topical corticosteroids and antiglaucomatous drops until the hyphema was resolved. CONCLUSION: ocular involvement, which is the most common extracutaneous 15 manifestation of juvenile xanthogranuloma, should be considered in the differential diagnosis of hypopyon and/or hyphema in young children.

Radiation-Induced Ocular Surface Disorders and Retinopathy: Ocular Structures and Radiation Dose-Volume Effect.

PURPOSE: This study aimed to evaluate the radiation-induced adverse effects on ocular structures in head and neck cancer patients and investigate the radiation dose-volume effects on the cornea, lacrimal gland, retina, optic nerve and chiasm. MATERIALS AND METHODS: A total of 38 eyes of 19 patients were included in this prospective, cohort study. All patients underwent complete ophthalmological examination in addition to contrast sensitivity, visual field and visual evoked potentials (VEP) tests. Ophthalmological examinations and psychophysical tests were performed in 6th, 12th, 18th, 24th months and in the last visit. The relationship between the ophthalmologic findings, and the radiation doses below and above the cut-off values was evaluated. RESULTS: Contrast sensitivity decrease and visual field deterioration were observed in 42% of the patients in the last visit (median 26 months) whereas a prolonged latency and decreased amplitude of P100 wave in VEP was observed in 58% and 33% of the eyes, respectively at 24th month. Totally 16 patients (84.2%) developed dry eye disease and eight of them received radiotherapy below tolerance doses and had mild to moderate dry eye findings. Radiation-induced retinopathy was observed in three of the eyes in eight patients who received radiation above tolerance dose. CONCLUSION: Head and neck cancers treated with radiotherapy, resulted in various ophthalmic complications. All patients who are treating with radiotherapy should be evaluated by an ophthalmologist in terms of anterior and posterior segment damage, even if the radiation dose is below the tolerance limit.

Aflibercept Treatment Results and Association with Baseline Characteristics in Cases of Newly Diagnosed Neovascular Age-Related Macular Degeneration

Objectives: To evaluate functional and anatomical responses to intravitreal aflibercept (IVA) treatment in newly diagnosed and untreated neovascular age-related macular degeneration (nvAMD) cases and to investigate the effect of baseline lesion characteristics on anatomical responses. Materials and Methods: This prospective, cross-sectional study included a series of 139 eyes of 133 patients that were diagnosed with active nvAMD and had not been treated. All eyes were subjected to complete ophthalmological examination, spectral-domain optical coherence tomography and fluorescein angiography, and 42 eyes also underwent indocyanine green angiography. IVA treatment was performed using a "treat and extend" regimen after 3 injections at 4-6 weeks intervals. Anatomical and functional responses at 4 weeks after the last injection were evaluated in eyes that completed 3 injections and the subgroup of eyes that completed 6 IVA injections. The effect of baseline lesion characteristics on IVA treatment results was also investigated. Results: All 139 eyes included in the study received 3 IVA injections (group 1) and 62 received 6 IVA injections. Both groups showed statistically significant improvement in best-corrected visual acuity (p<0.001 for both). The rate of complete response was 54.6% and 58.0% in groups 1 and 2, respectively. In group 1, the presence of pigment epithelial detachment (PED) and serous PED were identified as negative initial factors (p=0.043, p=0.005, respectively). However, none of the baseline characteristics were significantly associated with anatomical response in group 2. Conclusion: In our study, it was determined that successful anatomical and functional results were achieved with 3 and 6 doses of IVA in eyes with newly-diagnosed and untreated nvAMD. Among baseline characteristics, the presence of PED and serous PED in particular were found to be factors affecting treatment response negatively.

Multimodal Imaging Characteristics of Quiescent Type 1 Neovascularization in Best Vitelliform Macular Dystrophy

This case report of a 38-year-old man with bilateral Best vitelliform macular dystrophy (BVMD) presents bilateral quiescent type 1 neovascularizations (NV) detected by optical coherence angiography (OCTA) and their multimodal imaging characteristics. It was emphasized that this kind of quiescent and asymptomatic NV may be present in nearly every stage of BVMD and it was concluded that OCTA is a noninvasive, easy, and rapid method that is superior to other imaging methods in detecting them.

Early localized alterations of the retinal inner plexiform layer in association with visual field worsening in glaucoma patients.

Glaucoma is a chronic neurodegenerative disease of the optic nerve and a leading cause of irreversible blindness, worldwide. While the experimental research using animal models provides growing information about cellular and molecular processes, parallel analysis of the clinical presentation of glaucoma accelerates the translational progress towards improved understanding, treatment, and clinical testing of glaucoma. Optic nerve axon injury triggers early alterations of retinal ganglion cell (RGC) synapses with function deficits prior to manifest RGC loss in animal models of glaucoma. For testing the clinical relevance of experimental observations, this study analyzed the functional correlation of localized alterations in the inner plexiform layer (IPL), where RGCs establish synaptic connections with retinal bipolar and amacrine cells. Participants of the study included a retrospective cohort of 36 eyes with glaucoma and a control group of 18 non-glaucomatous subjects followed for two-years. The IPL was analyzed on consecutively collected macular SD-OCT scans, and functional correlations with corresponding 10-2 visual field scores were tested using generalized estimating equations (GEE) models. The GEE-estimated rate of decrease in IPL thickness (R = 0.36, P<0.001) and IPL density (R = 0.36, P<0.001), as opposed to unchanged or increased IPL thickness or density, was significantly associated with visual field worsening at corresponding analysis locations. Based on multivariate logistic regression analysis, this association was independent from the patients' age, the baseline visual field scores, or the baseline thickness or alterations of retinal nerve fiber or RGC layers (P>0.05). These findings support early localized IPL alterations in correlation with progressing visual field defects in glaucomatous eyes. Considering the experimental data, glaucoma-related increase in IPL thickness/density might reflect dendritic remodeling, mitochondrial redistribution, and glial responses for synapse maintenance, but decreased IPL thickness/density might correspond to dendrite atrophy. The bridging of experimental data with clinical findings encourages further research along the translational path.

Subgroups and Features of Poor Responders to Anti-Vascular Endothelial Growth Factor Treatment in Eyes with Neovascular Age-Related Macular Degeneration

Objectives: This study aimed to determine the incidence of poor response to intravitreal (IV) anti-VEGF treatment in neovascular age-related macular degeneration (nvAMD) and to define subgroups of poor responders. Materials and Methods: A total of 235 treatment-naive eyes of 202 patients completed this prospective study. Patients younger than 50 years of age and those with a contraindication for anti-VEGF therapy were excluded. All eyes were treated with IV ranibizumab. Poor response was defined as recurrence, persistence, or worsening despite treatment. Poor responders were classified into subgroups based on progression patterns. Results: Of the 235 eyes, 78 (33.2%) showed poor response. Pigment epithelial detachment (PED) and occult choroidal neovascularization (CNV) were more common among poor responders (p<0.001) and 5 subgroups were identified. Conclusion: Poor response to anti-VEGF treatment is not uncommon and occult CNV and PED are frequently seen in these eyes. Various subgroups can be defined based on clinical features.

Transgenic inhibition of astroglial NF-κB restrains the neuroinflammatory and neurodegenerative outcomes of experimental mouse glaucoma.

BACKGROUND: Glia-driven neuroinflammation promotes neuron injury in glaucoma that is a chronic neurodegenerative disease of the optic nerve and a leading cause of irreversible blindness. Although therapeutic modulation of neuroinflammation is increasingly viewed as a logical strategy to avoid inflammatory neurotoxicity in glaucoma, current understanding of the molecular regulation of neuroinflammation is incomplete, and the molecular targets for immunomodulation remains unknown. Growing datasets pointed to nuclear factor-kappaB (NF-κB), a key transcriptional activator of inflammation, which was identified to be most affected in glaucomatous astroglia. Using a cell type-specific experimental approach, this study aimed to determine the value of astroglial NF-κB as a potential treatment target for immunomodulation in experimental mouse glaucoma. METHODS: Neuroinflammatory and neurodegenerative outcomes of experimental glaucoma were comparatively analyzed in mice with or without cre/lox-based conditional deletion of astroglial IκKß, which is the main activating kinase involved in IκB degradation through the canonical pathway of NF-κB activation. Glial responses and the inflammatory status of the retina and optic nerve were analyzed by cell morphology and cytokine profiling, and neuron structure and function were analyzed by counting retinal ganglion cell (RGC) axons and somas and recording pattern electroretinography (PERG) responses. RESULTS: Analysis of glial inflammatory responses showed immunomodulatory outcomes of the conditional transgenic deletion of IκKß in astroglia. Various pro-inflammatory cytokines known to be transcriptional targets for NF-κB exhibited decreased production in IκKß-deleted astroglia, which included TNF-α that can induce RGC apoptosis and axon degeneration during glaucomatous neurodegeneration. Indeed, transgenic modulation of inflammatory responses by astroglial IκKß deletion reduced neurodegeneration at different neuronal compartments, including both RGC axons and somas, and protected PERG responses. CONCLUSIONS: The findings of this study support a key role for astroglial NF-κB in neuroinflammatory and neurodegenerative outcomes of experimental glaucoma and the potential of this transcriptional regulator pathway as a glial treatment target to provide neuroprotection through immunomodulation. By pointing to a potential treatment strategy targeting the astroglia, these experimental findings are promising for future clinical translation through transgenic applications to improve the treatment of this blinding disease.

Immunomodulation as a Neuroprotective Strategy for Glaucoma Treatment.

PURPOSE OF REVIEW: This review aims to highlight the current knowledge about inflammatory mechanisms of neurodegeneration in glaucoma with emphasis on potential immunomodulation strategies. RECENT FINDINGS: Glaucomatous retina and optic nerve present multiple evidences of inflammatory responses of astroglia, microglia, and blood-born immune cells. Although adaptive/protective responses of resident or systemic immune cells can support neurons and promote tissue repair mechanisms after injurious insults, prolonged inflammatory processes can also produce neurotoxic mediators. Treatments targeting these neurodestructive outcomes may restore immune homeostasis and protect neurons from inflammatory injury. Due to widespread and chronic nature of neuroinflammation in glaucoma, immunomodulation offers a treatment strategy to protect different neuronal compartments of RGCs during the chronic and asynchronous course of neurodegeneration. Uncovering of distinct molecular responses and interactions of different immune cells that determine the neuroinflammatory phenotype and participate in neurodegenerative outcomes will be critical to develop effective strategies for immunomodulation in glaucoma. SUMMARY: Neuroinflammation has increasingly been recognized to play an important role in glaucomatous neurodegeneration, and its modulation appears to be a promising treatment strategy for neuroprotection.

Vitreomacular Traction and Outer Retinal Structural Changes

In this case report we aimed to present the outer retinal structural changes secondary to vitreomacular traction (VMT). Outer retinal structural changes occurring secondary to VMT due to incomplete posterior vitreous detachment were described retrospectively with spectral-domain optical coherence tomography in 3 eyes of 3 patients. The patients ranged in age from 58 to 65 years and best corrected visual acuity in the 3 eyes was 4/10, 8/10, and 9/10. All of the patients were symptomatic and exhibited outer retinal microholes at the fovea extending from the retinal pigment epithelium to outer limiting membrane, with an overlying operculum on the detached posterior hyaloid membrane over the macula following spontaneous resolution of VMT. In the mean follow-up period of 32 months, the outer retinal microholes decreased in size but did not completely resolve. As demonstrated in these cases, VMT can cause small outer retinal layer defects without signs of full-thickness macular hole. These lesions can cause symptoms and affect visual function, and may be permanent structural changes.

Treatment results in aphakic patients with glaucoma following congenital cataract surgery.

PURPOSE: To evaluate the clinical findings and possible risk factors of patients with aphakic glaucoma following congenital cataract surgery and identify the factors affecting response to glaucoma treatment. METHODS: A retrospective chart review of 173 patients was performed who underwent congenital cataract surgery before the age of 12 months and 40 eyes of 25 patients with aphakic glaucoma were enrolled. Age of the patients at the time of the cataract surgery, postoperative complications, additional ocular pathologies and the type of glaucoma treatment needed were investigated. RESULTS: Mean age of 25 patients at the time of cataract surgery was 3.31 ± 2.28 (range 1-11) months with a mean follow-up period of 79 ± 30.5 (32-176) months. Out of 40 eyes, medical therapy was effective in 20 (50%) eyes, whereas 20 (50%) eyes needed surgery for glaucoma. In these 20 eyes, 6 (30%) eyes underwent only 1, 4 (20%) eyes underwent 2 and 10 (50%) eyes underwent 3 or more procedures. Age at the time of cataract surgery, pupillary membrane formation and additional ocular pathologies were not significantly associated both with the need for glaucoma surgery or the number of operations (p ≥ 0.05). CONCLUSION: Aphakic glaucoma following congenital cataract surgery is a serious complication which requires surgery in half (50%) of the patients. Usually, more than one surgical procedure (70%) is needed. It can be detected even years after cataract surgery (range 0.3-94 months), so long-term careful follow-up is necessary.
