Topical cyclosporine A and interferon alpha-2b as adjuvants to surgery to decrease pterygium recurrence.

BACKGROUND: Pterygium is very common in India and is usually removed by limbal conjunctival autograft transplantation (LCAT), which, despite being the first-line therapy, is still associated with recurrences of up to 18%. OBJECTIVES: To compare the safety and efficacy of topical cyclosporine A (CsA) and interferon (IFN) alpha-2b in the prevention of postoperative recurrence of pterygium. METHODS: A total of 40 patients with primary pterygium were randomized into two equal groups, Group C and Group I. Both the groups underwent LCAT, with Group C kept on topical cyclosporine 0.05% (CsA) 4 times daily and Group I on topical IFN alpha 2b 0.2 million IU 4 times daily postoperatively for 3 months. Pre- and posttreatment best-corrected visual acuity (BCVA), recurrence, and complications were assessed at day 1, week 1, 1 month, and 3 months. RESULTS: The mean preoperative BCVA of 0.51 ± 0.18 and 0.51 ± 0.23 improved to 0.13 ± 0.13 and 0.13 ± 0.13 in Group C and Group I, respectively, after 3 months of treatment (P < 0.0001). Recurrence was seen in 2 cases in Group C and in 1 case in Group I at 3 months. No significant complications occurred in either of the groups. CONCLUSION: Topical CsA and IFN Alpha-2b are newer efficacious adjuvants with LCAT for prevention of postoperative pterygium recurrence.

Comparison of topical steroids versus adjunctive intracameral triamcinolone versus posterior subtenon triamcinolone in pediatric cataract surgery.

Purpose: Prolonged postoperative topical corticosteroids are commonly given after pediatric cataract surgery to control inflammation. This study was undertaken to compare the efficacy, safety, and compliance of postoperative topical steroids and adjunctive intracameral (I/C) triamcinolone acetonide (tricort) and posterior subtenon (PST) triamcinolone in modulating postoperative inflammation after surgery. Methods: Forty-eight eyes of children with pediatric cataract between the ages of 5 and 10 years were randomized into three equal groups (T, I, S) before surgery. Group T received postoperative topical 1% prednisolone tapered over 4 weeks; Group I received adjunctive intraoperative I/C 1.2 mg/0.03 ml tricort and topical 1% prednisolone for 2 weeks postoperatively, and Group S received a single 0.5 ml (40 mg/ml) PST tricort without topical steroids. Signs of inflammation, intraocular pressure (IOP), and central corneal thickness were assessed at day 1, week 1, week 3, week 6, and week 12 postoperatively with optical coherence tomography (OCT) macula to rule out cystoid macular edema at the sixth and 12th weeks postoperatively. Results: Posterior synechiae were present in two eyes out of 16 in groups T and I, which resolved. Severe anterior chamber cells were present in four eyes out of 16 in group T, in two eyes in group I, and in one eye in group S, which resolved. All groups had comparable pre- and postoperative IOP. Conclusion: In pediatric cataracts, outcomes were better with PST tricort and the adjunctive I/C tricort compared to postoperative topical prednisolone, for modulating postoperative inflammation.

A comparison of sutureless flanged fixation and 4-point Gore-Tex fixation for scleral-fixated intraocular lenses: a pilot study.

Purpose: Scleral-fixation of intraocular lenses (IOLs) provides an option for eyes that lack sufficient capsular support for in-the-bag IOL placement. The latest techniques for lens fixation include use of a novel suture material, Gore-Tex, and a sutureless method, with flanged intrascleral fixation. The purpose of this pilot study was to compare these methods in terms of anatomic and clinical outcomes. Methods: A total of 35 eyes of patients 18-60 years of age who presented with aphakia, subluxated lens, or ectopia lentis were randomized into two groups. Group A (15 eyes) underwent flanged intrascleral IOL fixation using the Yamane technique; group B (20 eyes) underwent 4-point transscleral fixation of IOL using Gore-Tex suture. The following parameters were compared between groups on day 1, week 3, and month 6 postoperatively: logMAR uncorrected and best-corrected visual acuity, retinoscopy, IOL centration on slit-lamp biomicroscopy, and IOL tilt on ultrasound biomicroscopy. Results: Postoperative visual acuity was better in group B: uncorrected, logMAR 0.89 ± 0.22 versus 0.72 ± 0.24 (P = 0.046); best-corrected, logMAR 0.51 ± 0.18 versus 0.37 ± 0.26 (P = 0.016). No significant difference was found in postoperative retinoscopy and astigmatism between groups. IOL tilt (>100 µm) occurred in 8 cases in group A and in 9 cases in group B; 87% in group A and 100% in group B were well centered. Complications in both groups were minimal. Conclusions: In our small study cohort, both sutureless flanged IOL fixation and Gore-Tex sutured scleral IOL fixation resulted in excellent visual rehabilitation of patients with aphakia and subluxated lenses. Patients who underwent Gore-Tex suture fixation experienced better postoperative visual acuity, IOL centration, and stability.

"See-saw" Marcus Gunn syndrome.

The authors report an unusual case of Marcus Gunn syndrome in an adult patient, characterized by classical Marcus Gunn on one side and inverse Marcus Gunn on the other side. The patient exhibited a "see-saw" kind of eyelid movement on opening and closing the mouth and on moving the jaw from side to side. This clinical entity has been reported very rarely. A similar but etiologically different acquired condition seen commonly in adults, Marin Amat syndrome, is also discussed.

Abnormal ocular electrophysiology in Sjögren-Larsson syndrome.

Two siblings who were born out of consanguineous marriage in an Indian family and had typical clinical manifestations of Sjögren-Larsson syndrome were found to have normal electroretinogram and abnormal visual evoked potential results. Abnormal visual evoked potential results along with the presence of distinctive foveal and parafoveal deposits, which could have a prognostic bearing on the visual acuity of the patients, emphasize the importance of a complete ophthalmological and electrophysiological evaluation in all patients with Sjögren-Larsson syndrome.

Comparison of Manual Capsulorhexis and 25-Gauge Vitrectorhexis in Pediatric Cataract Surgery: A Pilot Study.

PURPOSE: To compare short-term visual outcomes (best corrected visual acuity [BCVA]), visual axis opacification, anterior (ACCC) and posterior (PCCC) continuous curvilinear capsulorhexis size, shape, and extension, and their decentration between manual capsulorhexis and 25-gauge vitrectorhexis in pediatric cataract surgery with intraocular lens (IOL) implantation. METHODS: Thirty eyes of children aged 3 to 8 years with developmental cataract were randomly selected for ACCC and PCCC by manual capsulorhexis forceps and 25-gauge vitrectomy cutter followed by IOL implantation and limited anterior vitrectomy. The size of the ACCC and PCCC was measured intraoperatively with calibrated capsulorhexis forceps. Patients were followed up for 3 months postoperatively and were evaluated for BCVA and visual axis opacification. Slit-lamp photographs of operated eyes were taken in retroillumination. The size in millimeters and decentration of the ACCC and PCCC from the center of the IOL were measured with the help of the Python imaging library. RESULTS: There was no statistically significant difference between BCVA (P > .05), visual axis opacification (P > .05), size of the ACCC (P > .05) and its decentration (P > .05), extension of the rhexis (P > .05), and size of the PCCC (P > .05) and its decentration (P > .05) between the two methods. CONCLUSIONS: In both groups, BCVA, visual axis opacification, and ACCC and PCCC size, shape, and decentration from the center of the IOL were comparable, making 25-gauge vitrectorhexis a good alternative to manual capsulorhexis.

Comparison of Plusoptix S12R photoscreener with cycloplegic retinoscopy and autorefraction in pediatric age group.

Purpose: To compare refractive measurements of noncycloplegic photoscreener Plusoptix S12R with cycloplegic retinoscopy, noncycloplegic autorefractor, and cycloplegic autorefractor in children. Methods: The study population (200 eyes of 100 children) was divided into two groups: Group 1 (age 3-7 years) and Group 2 (age 8-15 years). In Group 1, Plusoptix was compared with cycloplegic retinoscopy. In Group 2, Plusoptix was compared with cycloplegic retinoscopy and autorefraction. The second group was made because the younger group was found to be uncooperative for autorefraction. Paired t-test and Pearson's correlation were used for statistical analysis. Results: The mean difference in sphere (DS), spherical equivalent (DSE), and cylinder (DC) between cycloplegic retinoscopy and Plusoptix in Group 1 was 0.68 ± 0.55 (P < 0.001), 0.77 ± 0.61 (P < 0.001), and 0.18 ± 0.28 (P < 0.001), respectively. In Group 2, DS, DSE, and DC between cycloplegic retinoscopy and Plusoptix were 0.86 ± 0.49 (P < 0.001), 0.97 ± 0.51 (P < 0.001), and 0.23 ± 0.28 (P < 0.001); between cycloplegic autorefractor and Plusoptix were 0.69 ± 0.47 (P < 0.001), 0.74 ± 0.49 (P < 0.001), and 0.10 ± 0.31 (P = 0.002); and between noncycloplegic autorefractor and Plusoptix were - 0.25 ± 0.39 (P < 0.001), -0.19 ± 0.41 (P < 0.001), and 0.11 ± 0.31 (P < 0.001), respectively. Pearson's correlation coefficients of S, SE, and C between Plusoptix and cycloplegic retinoscopy were 0.948, 0.938, and 0.924 in Group 1 and 0.972, 0.972, and 0.946 in Group 2, and these values were statistically significant. Bland-Altman plots showed good agreement between cycloplegic retinoscopy and Plusoptix in both groups. Plusoptix gave axis values within 10° of cycloplegic retinoscopy in 81.56% of eyes in Group 1 and in 71.44% of eyes in Group 2. Conclusion: Plusoptix photoscreener can be used for prescription of axis of cylinder in children; however, other refractive measurements must be refined by cycloplegic retinoscopy.

Effect of Cycloplegia on Optical Biometry in Pediatric Eyes.

PURPOSE: To study the effect of cycloplegia on optical biometry parameters in pediatric eyes using the Lenstar LS 900 (Haag-Streit, Koeniz, Switzerland). METHODS: In this observational and comparative study, 56 normal eyes and 20 cataractous eyes in children between 5 and 15 years of age were included. Measurements were taken before and after cycloplegia using 2% homatropine drops. Parameters studied were axial length, central corneal thickness, keratometry, anterior chamber depth, and lens thickness. The Wilcoxon test was used to compare the effects of cycloplegia on all parameters. RESULTS: Cycloplegia resulted in a statistically significant decrease in axial length (P < .05), central corneal thickness (P < .05), and lens thickness (P < .001) and an increase in the anterior chamber depth (P < .001) in normal eyes. In the cataract group, cycloplegia resulted in an increase in anterior chamber depth (P < .001) and decrease in lens thickness (P < .001). CONCLUSIONS: Biometry measurements have to be carefully interpreted in pediatric eyes where cycloplegia is an important part of the examination.

Foveal neovascularization in a patient with Type 2 diabetes mellitus.

Retinal neovascularization in Diabetes mellitus (DM) is commonly seen at the optic disc and mid-periphery. It is rare at the fovea as the fovea is an avascular zone and there are very few case reports of foveal neovascularization in Type 1 DM. We report a case of unilateral foveal neovascularization in Type 2 DM.

Intravitreal Diclofenac in the Treatment of Macular Edema Due to Branch Retinal Vein Occlusion.

BACKGROUND AND OBJECTIVE: To evaluate the effect of a single dose of intravitreal diclofenac on macular edema (ME) due to branch retinal vein occlusion (BRVO). PATIENTS AND METHODS: In this prospective, interventional case series, 15 eyes with BRVO and ME with central macular thickness (CMT) greater than 250 µm on spectral-domain optical coherence tomography (SD-OCT) were enrolled. All patients were given 0.05 mg/0.1 mL of intravitreal diclofenac under aseptic conditions and followed up for 3 months with respect to best-corrected visual acuity (BCVA), intraocular pressure (IOP), fundus fluorescein angiography, and CMT measured on OCT. RESULTS: The mean visual acuity improved from 0.115 ± 0.03 preoperatively to 0.356 ± 0.29 at 3 months (P = .002). Mean line improvement was 2.2 ± 1.6. Mean preoperative CMT decreased from 453.2 µm ± 55.3 µm to 340.47 µm ± 101 µm at 3 months postoperatively (P = .001). The mean preoperative IOP was 16.4 mm Hg ± 1.59 mm Hg, whereas the mean postoperative IOP was 16.6 mm Hg ± 1.58 mm Hg (P = .08). None of the 12 phakic eyes showed evidence of cataract progression. CONCLUSION: Intravitreal diclofenac is safe and effective in improving BCVA and decreasing CMT in patients with BRVO and ME.

Comparison of Transcorneal and Pars Plana Routes in Pediatric Cataract Surgery in Infants Using a 25-Gauge Vitrectomy System.

PURPOSE: To demonstrate and compare the performance of the 25-gauge transconjunctival sutureless vitrectomy system via anterior (transcorneal) and posterior (pars plana) routes in congenital cataracts in infants. METHODS: In this prospective interventional study, 12 pediatric patients younger than 1 year with bilateral congenital cataract were included to undergo cataract surgery with posterior vitreorhexis and limited anterior vitrectomy using a 25-gauge vitrectomy system. One eye of each patient was operated on by the anterior (transcorneal) route and the other by the posterior (pars plana) route. All eyes were left aphakic. Intraoperative and postoperative (12 months after surgery) results were compared between the two routes, including visual axis opacification and astigmatism. All eyes were rehabilitated with contact lenses or spectacles. RESULTS: The 25-gauge vitrectomy system allowed excellent intraoperative control in both groups. Postoperatively, there was minimal conjunctival congestion, corneal edema, and inflammatory reaction. No intra-operative or postoperative complications were noted in any eye. All eyes had a clear visual axis 12 months after surgery. Mean spherical equivalent was 15.50 ± 2.28 diopters (D) and mean astigmatism was 0.25 ± 0.45 D in the transcorneal group, whereas in the pars plana group it was 15.46 ± 2.45 D and 0.16 ± 0.39 D, respectively, at 12 months, the difference being statistically insignificant (P > .05). CONCLUSIONS: The 25-gauge vitrectomy system allows sutureless surgery with excellent intraoperative control and minimal postoperative inflammation and astigmatism with clear visual axis by both the transcorneal and pars plana routes.

Phacoemulsification after penetrating keratoplasty with autologous limbal transplant and amniotic membrane transplant in chemical burns.

We report a patient who had earlier penetrating keratoplasty with amniotic membrane transplant and autologous limbal cell transplant for chemical injury who underwent cataract surgery by phacoaspiration. A posterior limbal incision with corneal valve was made superotemporally with extreme caution to avoid damage to the limbal graft. Aspiration flow rates and vacuum were kept low to avoid any turbulence during surgery. A 6.0 mm optic diameter acrylic foldable intraocular lens was inserted in the bag. The patient achieved a best-corrected visual acuity of 6/12 at 10 months' follow-up with a clear corneal graft. We conclude that caution during wound construction and phacoaspiration can help preserve corneal and limbal graft integrity in patients undergoing cataract surgery after corneal graft and limbal transplantation.

Full-thickness macular hole in Bartonella henselae neuroretinitis in an 11-year-old girl.

Cat scratch disease is a febrile illness caused by Bartonella henselae and is associated with rash at the site of cat bite or scratch and regional lymphadenopathy. Various ocular manifestations of cat scratch disease have been described, mainly retinochoroiditis, optic disc swelling, neuroretinitis, vascular occlusive events, serous retinal detachment, vitreous hemorrhage, intermediate uveitis, inflammatory lesions of the optic nerve head and rarely full thickness macular hole. We describe a case of an 11-year-old girl who presented 2 weeks after the onset of symptoms, with B. Henselae neuroretinitis with full thickness macular hole at presentation.

Bilateral optic disc pit with maculopathy in a patient with cleft lip and cleft palate.

Optic disc pit (ODP) is small, gray-white, oval depression found at the optic nerve head. It is a congenital defect that occurs due to imperfect closure of superior edge of the embryonic fissure. Cleft lip and palate are also congenital midline abnormalities occurring due to defect in the fusion of frontonasal prominence, maxillary prominence and mandibular prominence. There is only one case report describing the occurrence of ODP in a young patient with cleft lip and palate who also had basal encephalocele. We describe a 52-year-old patient with congenital cleft lip and palate with bilateral ODP with maculopathy but without any other midline abnormality.

Inverted mucoepidermoid papilloma of conjunctiva in a child.

Inverted papillomas are benign epithelial tumors usually arising from the mucous membrane of the sinonasal cavity and the urinary tract. Similar tumors of the conjunctiva are much rarer. We describe a case of juxtalimbal inverted papilloma in an 11-year-old boy who presented with a pigmented lesion that simulated a conjunctival nevus. Excisional biopsy established the diagnosis of inverted papilloma. The patient was carefully followed for 2 years, because the tumor's behavior in the conjunctiva is unknown. There was no recurrence of the lesion.

The Optical Performance of Spherical and Aspheric Intraocular Lenses in Pediatric Eyes: A Comparative Study.

PURPOSE: To compare the optical performance of aspheric intraocular lenses (IOLs) designed to correct the corneal spherical aberration versus spherical IOLs in pediatric eyes after cataract surgery. METHODS: In this prospective study, 40 eyes of patients 6 to 16 years old with developmental cataract were randomly assigned to receive a spherical IOL or an aspheric IOL after pediatric cataract surgery. At 3 months postoperatively, the outcomes compared between the two groups were best-corrected visual acuity, contrast sensitivity, and wavefront aberrometry. RESULTS: The mean best-corrected visual acuity was 0.32 ± 0.19 logMAR in the spherical IOL group and 0.28 ± 0.16 logMAR in the aspheric IOL group (P = .179). The aspheric IOL group showed better contrast sensitivity at 1.5, 3, and 6 cycles per degree than the spherical IOL group (P < .05). Total ocular aberrations, higher-order aberrations, and spherical aberrations were significantly lower in the aspheric IOL group (P < .05). CONCLUSIONS: The results suggest that aspheric IOLs compensate for the spherical aberration of pediatric eyes. In comparison to spherical IOLs, eyes with aspheric IOLs had decreased ocular aberrations, particularly spherical aberration, which contributed to better contrast sensitivity in these eyes. Further studies are required to evaluate the role of aspheric IOLs in children.

Functional outcomes of acrylic intraocular lenses in pediatric cataract surgery.

PURPOSE: To evaluate the functional outcomes of in-the-bag implantation of acrylic intraocular lenses (IOLs) with posterior continuous curvilinear capsulorhexis (PCCC), without PCCC, with PCCC and anterior vitrectomy, and with PCCC and optic capture in pediatric cataract surgery. SETTING: Pediatric Ophthalmology Service, Guru Nanak Eye Centre, New Delhi, India. METHODS: Forty-two eyes of 25 children were included in this prospective study. All eyes had in-the-bag implantation of an AcrySof IOL (Alcon). Twenty-five eyes had had an anterior continuous curvilinear capsulorhexis (ACCC) (Group A). Seventeen eyes had PCCC along with ACCC (Group B), 4 had anterior vitrectomy combined with PCCC (Group C), and 6 had PCCC with IOL optic capture through the PCCC (Group D). Secondary opacification of the visual axis, visual acuity, and possible complications were observed and analyzed. RESULTS: The mean age of the patients was 78 months (range 36 to 144 months). The mean follow-up was 13 months (range 6 to 18 months). Four eyes (16%) in Group A developed visually significant posterior capsule opacification (PCO) involving the central visual axis and required secondary capsulotomy. All eyes in Groups B, C, and D had a clear visual axis at the last follow-up and did not require a secondary procedure. Minimal postoperative inflammation (ie, aqueous flare and IOL deposits ) was seen in all groups. The mean preoperative decimal best corrected visual acuity (BCVA) in Groups A, B, C, and D was 0.095, 0.055, 0.174, and 0.039, respectively. Postoperatively, the BCVA was 0.54, 0.66, 0.66, and 0.66, respectively. CONCLUSIONS: An optimal-sized ACCC followed by in-the-bag implantation of a foldable acrylic IOL helped maintain a clear visual axis by delaying the onset of PCO and leading to milder PCO. The benefits of a foldable acrylic IOL in pediatric cataract surgery can be increased by combining it with PCCC, with or without anterior vitrectomy, or with optic capture of the IOL.

Posterior continuous curvilinear capsulorhexis with and without optic capture of the posterior chamber intraocular lens in the absence of vitrectomy.

PURPOSE: To evaluate the efficacy of posterior continuous curvilinear capsulorhexis (PCCC) with optic capture of the posterior chamber intraocular lens (PC IOL) in the absence of vitrectomy in preventing secondary opacification of the visual axis following pediatric cataract surgery. PATIENTS AND METHODS: Thirty-four eyes of 28 children with congenital or developmental cataract, aged 1.5 to 12 years (mean, 6.39 years), were included in this prospective, randomized study. Anterior continuous curvilinear capsulorhexis (ACCC) with PCCC without optic capture of the PC IOL was performed in group A (18 eyes) and ACCC with PCCC with optic capture of the PC IOL was performed in group B (16 eyes). None of the eyes underwent anterior vitrectomy. Secondary opacification of the visual axis, visual acuity, and possible complications were observed and analyzed. RESULTS: The follow-up period ranged from 8 to 28 months (mean, 17.5 months). All 16 eyes (100%) in group B had a clear visual axis at the end of follow-up. Eight eyes (44.4%) in group A had significant opacification of the visual axis. The difference between the two groups was statistically significant (P = .0011). No eye in group B required secondary intervention, whereas all 8 eyes in group A with significant secondary opacification required secondary intervention. There was no statistically significant difference in other complications such as anterior chamber reaction, fibrin formation, lenticular precipitates, and posterior synechiae. The final best-corrected visual acuity at the end of follow-up was comparable in the two groups (P > .05). CONCLUSION: PCCC with optic capture of the PC IOL prevents secondary opacification of the visual axis even in the absence of vitrectomy.

Penicillium keratitis in vernal Keratoconjunctivitis.

We report a case of penicillium keratitis in vernal shield ulcer in the absence of corticosteroid use. This report illustrates super-added infection in vernal shield ulcer by an organism which is otherwise innocuous and forms a part of the normal ocular flora.
