RESUMEN
Purpose: The aim of the study was to evaluate the outcomes of cataract surgery in patients of the pediatric age group with systemic comorbidities. Methods: Medical records of 54 eyes (30 patients) of the pediatric age group with systemic comorbidities who had undergone cataract surgery in a tertiary?care center were reviewed. The following parameters were recorded: systemic comorbidity; toxoplasmosis, rubella, cytomegalovirus, herpes simplex, HIV (TORCH) profile, best spectacle?corrected visual acuity (BSCVA), strabismus, nystagmus, and cataract morphology. Results: Thirty patients with a mean age of 55 months (9 months–14 years) were included. On average, every child was seen by three physicians, and the mean duration between the first visit to a physician and presentation to our center was 2.23 ± 0.67 years. The various causes for delay in referral include multiple referrals due to a lack of general anesthesia services in 78% of cases, a long waiting list at the referral hospital in 35% of cases, and a lack of awareness at the primary?care physician level in 50% of cases. The mean BSCVA at presentation was 1.4 logMAR (0.3 to 3 logMAR). The most common cataract morphology was that of zonular cataract (31.48%; 17/54). Strabismus and abnormal eye movements were observed in 27.7% (15/54) and 33.3% (18/54) of eyes, respectively. Various systemic associations were periventricular leukomalacia (12/30), Down’s syndrome (6/30), seizure disorder (6/30), cardiac valvular anomalies (6/30), Marfan’s syndrome (4/30), hypothyroidism (4/30), rubella (3/20), cytomegalovirus (3/20), cerebral palsy (2/30), nephrotic syndrome (2/30), Type 1 diabetes mellitus (1/30), microcephaly (1/30), cryptogenic West syndrome (1/30), congenital rubella syndrome (1/30), and Tourette syndrome (1/30). The mean postoperative corrected distance visual acuity (CDVA) at 2?year follow?up improved to 1.0 logMAR (0 to 3 logMAR). No postoperative complications were reported at the final follow?up. Around 70% of the parents reported improvement in their child’s psychomotor skills. Conclusion: Intellectually impaired pediatric patients with cataract should be operated upon whenever there is a presence of infrastructure, and unnecessary delay in surgery should be avoided by referring the patient to higher centers. Even though objective improvement in visual acuity was suboptimal, there was definitely an improvement in the psychomotor skills of the patients.
RESUMEN
Purpose: To evaluate the outcomes of surgical intervention in cases of ectopia lentis. Methods: This retrospective study included all cases of ectopia lentis that presented between June 2015 and March 2019 in a tertiary care center. They were reviewed retrospectively. The corrected distance visual acuity (CDVA), severity of lens subluxation, type of surgery, intra?operative and post?operative complication, and specular count were recorded. Results: Seventy?eight eyes of 57 cases with a mean age at surgery of 14.73 years were analyzed. Intra?lenticular lens aspiration was the most common (n?62/78; 79.5%) surgical procedure followed by lens aspiration, intra?capsular cataract extraction, phaco?aspiration, and pars?plana lensectomy. Simultaneous intra?ocular lens (IOL) implantation was performed in 46.2% (n?32/78) of the eyes. The mean CDVA improved from 0.85 ± 0.55 logMAR to 0.44 ± 0.29 logMAR at 6 weeks follow?up. The post?operative CDVA was significantly better in the pseudo?phakic group compared to the aphakic group (p?0.02). The patient’s age at the time of surgery and the degree of subluxation did not impact the final visual outcome. Intra?operative complication included vitreous hemorrhage (n?1) and lens matter drop (n?1). Post?operative complications were noted in 26.9% of the eyes (n?21/78) with a higher complication rate in the pseudo?phakic group (p?0.00). A second intervention was required in 7.7% of the eyes (n?6/78). Conclusion: Age and degree of subluxation at the time of surgery do not influence the final visual outcome in cases of ectopia lentis undergoing lens extraction surgery. IOL implantation results in better visual outcomes but is associated with a high complication rate.
RESUMEN
We aimed describe the chronic ocular sequelae of Kindler syndrome. All cases of Kindler syndrome with ocular involvement that presented to a tertiary eye care center were included. Three cases of Kindler syndrome with ocular changes were reviewed. Case 1 (10 years, female) had recurrent epithelial breakdown with severe dry eye and corneal opacity secondary to keratitis. Case 2 (28 years, male) had symblepharon , ocular surface keratinization , and severe dry eye. Case 3 (16 years , female ) had partial limbal stem cell deficiency with dry eye. All cases were treated with topical lubricants, short course of low?potency steroids and immuno?modulators. Attention must be paid to the eye in addition to the oro?an?genital mucosa to avoid longterm ocular sequelae
RESUMEN
Purpose: To analyze the pattern of bacterial pathogens causing infective keratitis and their resistance to the recommended antibiotics over six years. Methods: It was a retrospective study of 9,357 cases of bacterial keratitis from January 2015 to December 2020, at a tertiary care ophthalmic center. A total of 9,547 corneal specimens were obtained from the study subjects. Demographic details of the patients, pathogenic bacteria isolated, and their antimicrobial susceptibility were noted and analyzed. Results: Bacterial pathogens were identified in 23.52% of the specimens. The most common isolates were coagulase?negative Staphylococci (60.75%), followed by Pseudomonas aeruginosa (14.23%), Staphylococcus aureus (13.92%), gram negative bacilli of the family Enterobacterales (8.64%), Streptococcus spp. (1.72%), Acinetobacter spp. (0.13%), and other non?fermenting gram?negative bacilli (0.57%). In Staphylococci, 55–80% of isolates were resistant to erythromycin, and 40–70% to fluoroquinolones, while no resistance was observed against vancomycin. 40–60% of isolates of P. aeruginosa were resistant to cephalosporins, 40–55% to fluoroquinolones, and 30–60% to aminoglycosides. Also, 40–80% of isolates of Enterobacterales were resistant to cephalosporins, and 50–60% to fluoroquinolones. Most gram?negative isolates were susceptible to carbapenems and polymyxin B. Conclusion: To the best of our knowledge, our study is the largest compilation of microbiological profile of bacterial keratitis from North India. It highlights the current trend of the bacterial pathogens that cause infectious keratitis. Staphylococci and Pseudomonas were found to be the most common pathogens. Increased resistance was seen against some of the commonly prescribed empirical antibiotics. Such evidence is useful for restructuring the empirical prescription practices from time to time.
RESUMEN
Purpose: To formulate a treatment algorithm for the management of descemetocele. Methods: This was a prospective interventional study that was conducted at a tertiary eye?care center. All consecutive cases of descemetocele during the study period (April 1, 2017–March 31, 2018) were evaluated for the following parameters: age, sex, previous medical or surgical therapy, risk factors, preexisting ocular diseases, location, site and size of descemetocele, interventions undertaken, visual acuity, and the fellow eye status. The surgical modalities and fellow eye status were correlated individually with therapeutic and functional outcomes, based on which a treatment algorithm was formulated. Results: The study included 24 eyes of 24 patients (19M, 5F) with a median age of presentation of 45 years. The mean follow?up duration was 6.79 ± 3.97 months (3–12 months). The most common cause of descemetocele was microbial keratitis (66.66%), and most cases were central (50%), small (58.33%), and non?perforated (79.16%). The surgical interventions undertaken were cyanoacrylate glue (CG, 37.5%), penetrating keratoplasty (PKP, 33.33%), patch graft (16.66%), and deep anterior lamellar keratoplasty (DALK, 12.5%). Therapeutic success was noted in 13/24 eyes (54.16%). Final visual acuity > 3/60 was seen in 25% cases. Suboptimal therapeutic (P = 0.07) and visual (P = 0.34) outcomes were noted in subjects with non?functional fellow eye. Conclusion: PKP was preferred for descemetoceles with active microbial keratitis and extensive infiltrates, while CG and DALK were undertaken for healed microbial keratitis, neurotrophic keratitis, and ocular surface disorders with partial limbal stem cell deficiency (LSCD). For total LSCD, amniotic membrane graft was preferred.
RESUMEN
Purpose: To describe the surgical results of concomitantly performed optical penetrating keratoplasty (PKP) with glued intrascleral haptic fixation (ISHF). Methods: Retrospective review of 18 patients (15–72 years) with best?corrected visual acuity (BCVA) of ?1/60 subjected to unilateral concomitant optical PKP with ISHF and followed up for 13.11 ± 5.83 months (6–26 months) was undertaken. Results: The most common diagnoses were failed PKP (9/18, 50%) followed by aphakic bullous keratopathy (5/18, 27%). Preoperative glaucoma, peripheral anterior synechiae (PAS), and deep vascularization were present in 7/18 (38.88%), 12/18 (61.11%), and 5/18 (27.77%) patients, respectively. Intraoperatively, concomitant procedures such as pupilloplasty and intraocular lens explant were undertaken in 5/18 (27.277%) patients and 1/18 patients (5.55%) experienced suprachoroidal hemorrhage. At final follow?up, BCVA was ?6/60 in 50% patients (mean astigmatism: 4.79 ± 1.68D), and 55.55% cases experienced graft failure (90% failed within one year of surgery). The most common causes of graft failure were glaucoma (50%), glaucoma with rejection (20%), rejection (10%), retinal detachment (10%), and suprachoroidal hemorrhage (10%). The ODDS ratio (OR) of having graft failure with the following factors was postoperative secondary interventions (OR: 6), postoperative complications (OR: 2.25), prior failed graft (OR: 1.8), preoperative PAS (OR: 1.75), intraoperative concomitant procedures (OR: 1.5), preoperative glaucoma (OR: 1.33), previous surgeries (OR: 1.24), and deep corneal vessels (OR: 0.66). Conclusion: All patients underlying PKP combined with glued ISHF must be counseled about suboptimal surgical outcomes. Emphasis is laid on appropriate case selection and stringent follow?up during the first year after surgery. Secondary interventions should be undertaken cautiously and judiciously in these patients
RESUMEN
Mycotic keratitis is a major cause of corneal blindness, especially in tropical and subtropical countries. The prognosis is markedly worse compared to bacterial keratitis. Delayed diagnosis and scarcity of effective antifungal agents are the major factors for poor outcome. Over the last decade, considerable progress has been made to rapidly diagnose cases with mycotic keratitis and increase the efficacy of treatment. This review article discusses the recent advances in diagnosis and management of mycotic keratitis with a brief discussion on rare and emerging organisms. A MEDLINE search was carried out for articles in English language, with the keywords, mycotic keratitis, fungal keratitis, emerging or atypical fungal pathogens in mycotic keratitis, investigations in mycotic keratitis, polymerase chain reaction in mycotic keratitis, confocal microscopy, treatment of mycotic keratitis, newer therapy for mycotic keratitis. All relevant articles were included in this review. Considering the limited studies available on newer diagnostic and therapeutic modalities in mycotic keratitis, case series as well as case reports were also included if felt important.
RESUMEN
Acute corneal hydrops is a condition characterized by stromal edema due to leakage of aqueous through a tear in descemet membrane. The patient presents with sudden onset decrease in vision, photophobia, and pain. Corneal thinning and ectasias combined with trivial trauma to the eye mostly by eye rubbing is considered as the underlying cause. With conservative approach self-resolution takes around 2 to 3 months. Surgical intervention is required in cases of non-resolution of corneal edema to avoid complications and for early visual rehabilitation. Intracameral injection of air or gas such as perflouropropane is the most common surgical procedure done. Recent investigative modality such as anterior segment optical coherence tomography is an extremely useful tool for diagnosis, surgical planning, and postoperative follow up. Resolution of hydrops may improve the contact lens tolerance and visual acuity but most cases require keratoplasty for visual rehabilitation.
RESUMEN
Keratoconus is the most common corneal ectatic disorder, the cause of which is largely unknown. Many factors have been implicated, and the ocular allergy is being one of them. The commonly proposed pathogenesis includes the release of inflammatory mediators due to eye rubbing which may alter the corneal collagen and lead to corneal ectasias. The onset of keratoconus is often early in cases associated with allergy and routine corneal topography may detect subtle forms of keratoconus. These cases may require early keratoplasty and are at an increased risk of having acute corneal hydrops. Surgical outcomes are similar to primary keratoconus cases. However, post-operative epithelial breakdown may be a problem in these cases. Control of allergy and eye rubbing is the best measure to prevent corneal ectasias in cases of ocular allergy.
