ABSTRACT

OBJECTIVES: To evaluate the visual outcome of mini-scleral contact lenses (MSLs) in keratoconus following the resolution of acute hydrops. METHODS: This was a prospective observational case series of patients of healed hydrops in keratoconus fitted with an MSL (Keracare, Acculens, Lakewood, CO) who were managed for acute hydrops medically or surgically at least 3 months prior. Uncorrected visual acuity, best spectacles-corrected visual acuity, best lens-corrected visual acuity, topographic indices, keratometric indices, contact lens parameters, and ocular aberrometric changes were evaluated. All patients were followed up for at least 3 months. RESULTS: Eighteen eyes of 17 patients were included in the analysis. The mean post-hydrops topographic values of the eyes included flat keratometric value (K1) 64.93±10.88 (range 44.30-93.40) diopters (D), steep keratometric value (K2) 70.41±10.92 D (range 45.8-98.6 D), and Kmax of 79.53±17.73 D (range 50-130.2). The final mini-scleral lens's mean dioptric power was -8.56±3.96 D (range -18 to -4). Visual acuity significantly improved from post-hydrops resolution uncorrected visual acuity of 1.5±0.71 logMAR to 0.79±0.18 logMAR best spectacles-corrected visual acuity to 0.27±0.01 logMAR best lens-corrected visual acuity (P-value <0.0001). Similarly, there was considerable improvement in corneal aberrometric values after wearing an MSL. At the 3-month follow-up, 15 patients (16 eyes) were compliant to contact lens use with a minimum of 6 to 8 hr daily while two patients (2 eyes) were poorly compliant. CONCLUSIONS: A MSL is a valuable option for visual rehabilitation in keratoconus following the resolution of acute hydrops.

ABSTRACT

We describe and assess the efficiency of a novel technique of placing implantable collamer lens (ICL) footplates in the sulcus in poorly dilated pupils utilizing perioptic holes and two instruments simultaneously (Sinskey hook and ICL manipulator). Twelve eyes of 10 patients underwent ICL implantation through this technique. The technique employs a bimanual approach engaging perioptic holes in the eyes with intraoperative miosis. Perioptic holes were engaged with a Sinskey hook and pulled slightly back, while the footplates were tucked under the iris by using an ICL manipulator. All patients had uneventful surgery. At 1 week follow-up, uncorrected distance visual acuity (UCDVA) was -0.01 ± 0.04 logMAR with a mean vault of 606.17 ± 108.33 microns. No complications were noted. However, too small a pupil is a limiting factor; this technique can be of use in up to mid-dilated pupils. Bimanual placement of haptics of ICL may represent a safe and effective technique in insufficient mydriasis or intraoperative pupillary miosis.

ABSTRACT

We report the adjuvant role of oral doxycycline therapy for the management of early bleb leaks post mitomycin-augmented trabeculectomy. Two glaucoma patients, who underwent trabeculectomy with mitomycin C, presented with a low intraocular pressure (IOP) in the early postoperative period. Both patients had moderately elevated bleb with Seidel's positive test. Oral doxycycline 100 mg twice daily was given for 1 week in addition to routine postoperative management. Post doxycycline therapy at 1 week, healing of the wound was noted, with a negative Seidel's test. The IOP was maintained at 3 months postoperatively in both patients.

ABSTRACT

PURPOSE: To study the outcomes of topical Retinol Palmitate ophthalmic solution in chronic Stevens-Johnson Syndrome with ocular surface keratinisation. METHODS: It was a comparative interventional study conducted at Rajendra Prasad Centre for Ophthalmic Sciences, Delhi, India from 2020 to 2022 evaluating outcomes of addition of topical Retinol Palmitate to conventional treatment objectively as well as subjectively from baseline up to 12 weeks. RESULTS: A statistically significant improvement was seen in patients who received topical Retinol palmitate at 12 weeks in terms of Schirmer-1 test(p=<0.01), tear prism height on ASOCT(p = 0.02), Rose Bengal staining score of cornea(p = 0.01) and conjunctiva (p < 0.01), reduction of ocular surface keratinisation on impression cytology(p = 0.01) and subjective evaluation using OSDI questionnaire(p = 0.04).Impression cytology revealed goblet cells in Retinol palmitate group at 1 week after initiation of therapy, which increased further at 1 month follow up but reduced at 3 months. No goblet cells were seen in control group at any follow-up. No significant difference was noted between the two groups in terms of visual acuity, tear film breakup time, inflammatory cells on impression cytology and inflammatory markers in tears. CONCLUSION: Topical Retinol palmitate is a safe and effective drug in cases of chronic SJS with ocular surface keratinisation. It has the potential to reverse keratinisation of the ocular surface and promote development of goblet cells. However, the survival of goblet cells is not long lasting.

ABSTRACT

A 10-year-old child presented to eye casualty with pain, watering and photophobia of the left eye for one month. Parents gave a history of chuna (lime) falling inside the eye one month back, following which the patient consulted at a primary health centre. However, there was no relief of symptoms and the patient was referred to a higher centre. On examination under anaesthesia, the eye was full of chuna particles. Removal of all visible chuna particles and the corneal chuna plaque was planned. Intra-operatively, the stromal melt was noted around the corneal chuna plaque extending up to Descemet's membrane. Microscope-integrated optical coherence tomography (Mi-OCT) guided removal of corneal chuna particles was done. A tectonic deep anterior lamellar keratoplasty (DALK) along with amniotic membrane graft (AMG) and symblepharon ring placement was done. Two weeks post-operatively, the patient was having a persistent epithelial defect. A repeat AMG with a symblepharon ring was done. On one month follow-up, the epithelial defect had healed. This case emphasises the fact that ocular chemical injuries are an emergency requiring urgent and apt management. In cases of severe ocular chuna injury with delayed presentation, removal of all particles, maintenance of globe integrity and ocular surface restoration is a challenging goal. Healing is slow and visual prognosis is generally guarded in such cases.

ABSTRACT

Autoimmune polyendocrinopathy candidiasis ectodermal dystrophy (APECED) is a multisystemic rare genetic disorder characterised by abnormalities of the immune system. We report the ocular features of APECED in two siblings of an Indian family, out of four who are still living. The ocular features of this disorder primarily included madarosis, refractive error, heterochromia, corneal opacity and peripheral retinal pigment epithelium degeneration. There is marked phenotypical heterogeneity in this disorder. We found differences even between monozygotic twins. While one of the twins did not have any ocular issues, the other one did. The child with corneal involvement was the most symptomatic; however, it did not lead to visual impairment. On genetic workup, homozygous p.M1V mutation was found in exon 1 of AIRE gene that has not been studied in Indian subjects with APECED. To the best of our knowledge, there is no report in literature describing ocular features of APECED in an Indian family with distinctive genetic involvement.

ABSTRACT

Purpose: Real-life comparison of three intravitreal drug regimens used in cases of endophthalmitis at a tertiary care center in India. Methods: In this prospective, comparative study, patients of bacterial endophthalmitis were grouped according to intravitreal antibiotic drug regimens into Group 1 (ceftazidime and vancomycin), Group 2 (piperacillin + tazobactam and vancomycin), and Group 3 (imipenem and vancomycin). Forty-eight hours after injection nonresponding/worsening patients underwent vitrectomy. Vitreous samples were subjected to microbiological and pharmacokinetic tests. Results: A total of 64 patients were included and divided into Group 1: 29, Group 2: 20, and Group 3: 15 cases. Also, 75% of patients were post-surgical endophthalmitis, whereas 25% were post-traumatic. Improvement in vision (V90-0) and vision at 3 months (V90) were comparable between the three groups. Visual recovery was poorer in post-traumatic cases. In post-surgical cases, visual recovery was poorer in those presenting beyond 72 h of onset of symptoms (P = 0.0002). Polymerase chain reaction (PCR) positivity (66%) was higher than BACTECTM (33%) and culture (14%). Antibiotic resistance was comparable amongst the three groups. Most patients (62/64) further underwent vitrectomy. Ceftazidime and vancomycin achieved vitreous concentrations more than the minimum inhibitory concentration (MIC) at 48 h after the first injection. Conclusion: The choice of antibiotics did not affect the rate of vitrectomy and final vision in a real-life scenario. Ceftazidime and vancomycin can still be used as first-line intravitreal antibiotics owing to their comparable microbial sensitivity profile and adequate ocular bioavailability.

ABSTRACT

A man aged 26 years presented with complaints of diminution of vision in his right eye for 1 year following a fist injury. He had a history of laser-assisted in situ keratomileusis in both eyes 5 years earlier. On examination, his uncorrected distance visual acuity (UDVA) in the right eye was 1.0 logMAR. Slit-lamp examination of the right eye revealed a superotemporal dislocation of the flap with coexisting epithelial ingrowth encroaching the pupillary area. Due to the presence of long-standing fixed flap folds, a flap amputation was performed along with removal of the epithelial ingrowth using 0.02% mitomycin C as adjunct. Postoperatively, the UDVA was 0.3 logMAR on day 1, which improved to 0.2 logMAR at 1 week. At 1 year, the UDVA was 0.2 logMAR improving to 0.1 logMAR with refraction, with minimal paracentral corneal haze and no signs of corneal ectasia.

ABSTRACT

A 6.5-year-old boy with congenital hereditary endothelial dystrophy underwent clear corneal ultra-thin descemet stripping automated endothelial keratoplasty (DSAEK). After graft insertion, it was difficult to assess graft orientation due to hazy cornea. Intraoperative optical coherence tomography (iOCT) showed a well-attached graft and the bevelled edge of donor lenticule made an acute angle with the overlying stroma. Postoperative anterior segment OCT confirmed the presence of acute-angled bevel sign. A wetlab experiment was performed with experimental corneoscleral tissues to confirm the findings. Donor lenticule was injected in the artificial chamber with stromal-side up as well as stromal side-down. 'Acute-angled bevel sign' was observed on iOCT in the experimental cases with stromal-side up. In inverse graft, the acute-angled bevel was not observed, instead the configuration was obtuse angled. Identifying the 'acute-angled bevel sign' on iOCT confirms correct graft orientation after unfolding and is extremely useful for hazy corneas and ultrathin DSAEK lenticules.
