RESUMO
PURPOSE: Optic disk pit (ODP) is a subset of spectrum of congenital cavitary anomalies. Optic disk pit maculopathy causes progressive visual deterioration and is addressed with pars plana vitrectomy (PPV) with or without ODP stuffing. PATIENT AND METHODS: We report a case of progressive ODP maculopathy who was taken up for 23-G 3-port PPV, with complete vitreous removal and stuffing of the ODP with autologous sclera and sequential analysis of change in the retinal nerve fiber layer (RNFL) thickness. RESULTS: Spectral-domain optical coherence tomography RNFL analysis at 1 and 12 months follow-up postoperatively showed total RNFL thickness decrease from 130 µm to 103 µm respectively. Hemiquadrant analysis showed slight reduction of superior RNFL thickness from 142 µm to 139 µm. However, in the inferior hemiquadrant, the reduction in mean RNFL thickness seems to be significant from 133 µm to 100 µm at 1 and 12 months respectively. Sector-wise analysis of the RNFL thickness showed maximum reduction in the inferotemporal quadrant and other sectors seemed to be relatively preserved corresponding to the area of scleral stuffing. CONCLUSION: Retrospective or prospective analysis of RNFL health of patients undergoing surgery for ODP-M with stuffing needs to evaluated.

Purpose: To measure the levels of inflammatory factors in tear fluid of pre-term infants with and without retinopathy of prematurity (ROP). Methods: The cross-sectional pilot study included 29 pre-term infants undergoing routine ROP screening. Pre-term infants were grouped as those without ROP (no ROP; n = 14) and with ROP (ROP; n = 15). Sterile Schirmer's strips were used to collect the tear fluid from pre-term infants. Inflammatory factors such as interleukin (IL)-6, IL-8, MCP1 (Monocyte Chemoattractant Protein 1; CCL2), RANTES (Regulated on Activation, Normal T Cell Expressed and Secreted; CCL5), and soluble L-selectin (sL-selectin) were measured by cytometric bead array using a flow cytometer. Results: Birth weight (BW) and gestation age (GA) were significantly (P < 0.05) lower in pre-term infants with ROP compared with those without ROP. Higher levels of RANTES (P < 0.05) and IL-8 (P = 0.09) were observed in the tear fluid of pre-term infants with ROP compared with those without ROP. Lower levels of tear fluid IL-6 (P = 0.14) and sL-selectin (P = 0.18) were measured in pre-term infants with ROP compared with those without ROP. IL-8 and RANTES were significantly (P < 0.05) higher in the tear fluid of pre-term infants with stage 3 ROP compared with those without ROP. Tear fluid RANTES level was observed to be inversely associated with GA and BW of pre-term infants with ROP and not in those without ROP. Furthermore, the area under the curve and odds ratio analysis demonstrated the relevance of RANTES/BW (AUC = 0.798; OR-7.2) and RANTES/MCP1 (AUC = 0.824; OR-6.8) ratios in ROP. Conclusions: Distinct changes were observed in the levels of tear inflammatory factors in ROP infants. The status of RANTES in ROP suggests its possible role in pathobiology and warrants further mechanistic studies to harness it in ROP screening and management.

PURPOSE: The purpose was to study the anatomical and functional outcome following single low-dose suprachoroidal triamcinolone acetonide (LD-SCTA) (2 mg) injection in noninfectious posterior uveitis. METHODS: Eleven patients with macular edema (ME) more than 280 µ secondary to noninfectious uveitis were included in the study. A single LD-SCTA (0.5 ml) injection was performed in the study eye with the help of a novel suprachoroidal microneedle (Pricon, Iscon Surgicals, Jodhpur, Rajasthan, India). The study parameters were noted at 4 and 12 weeks post LD-SCTA injection. RESULTS: Ten of 11 patients had a significant decrease in central macular thickness (CMT). The mean CMT measurement at baseline was 513.6 ± 191.73 µm for the 10 patients who responded to the treatment, which reduced significantly to 265.1 ± 34.72 µm (P < 0.003) and 260.6 ± 34.72 µm (P < 0.002) at 4 and 12 weeks, respectively. The mean best-corrected visual acuity (BCVA) at baseline was 0.84 ± 0.41 logMAR unit which improved to 0.52 ± 0.33 (P < 0.001) and 0.25 ± 0.22 (P < 0.000) at weeks 4 and 12, respectively. The mean intraocular pressure at baseline recorded was 16.36 ± 2.97 mmHg, 19.45 ± 4.80 mmHg (P = 0.06) at 4 weeks, and 17.27 ± 2.53 mmHg (P = 0.35) at 12 weeks. One eye which did not respond to LD-SCTA was a case of recurrent Vogt-Koyanagi-Harada disease. CONCLUSION: Single LD-SCTA injection is efficacious in reducing CMT in ME, improving BCVA, and controlling the inflammation in noninfectious posterior uveitis. LD-SCTA can be used as a first-line therapy in noninfectious uveitis over other routes of steroid administration with a favorable outcome and safety profile.

Background In this study, we aimed to assess the outcomes of transcutaneous retrobulbar injection of amphotericin B (TRAMB) in rhino-orbital-cerebral mucormycosis (ROCM) among patients recovering from coronavirus disease 2019 (COVID-19). Methodology This retrospective study was conducted at a tertiary care center in eastern India from May 29th to July 31st, 2021, and included post-COVID-19 patients admitted with stage 3 and 4a ROCM who underwent TRAMB. The details of the ophthalmic examination, laboratory investigations, and radiological examination were retrieved from patients records. Patients were given TRAMB (3.5 mg/mL) on alternate days till they underwent debulking surgery and resumed from the second postoperative day alternatively till the patients showed clinical stabilization or improvement. Results In total, 45 eyes of 41 patients were included in the study. The median number of injections given was six (minimum = 3; maximum = 10). Following was the distribution of number of injection needed in each eye: eight eyes (three injections), six eyes (four injections), seven eyes (five injections), three eyes (six injections), eight eyes (seven injections), 11 eyes (eight injections), and one eye had received nine and ten injections each. Overall, 21/32 (65.62%) eyes had improvement in proptosis whereas 9/32 (28.12%) had improvement in ptosis. Six patients had improvement in extraocular movement. In total, 25 eyes had no improvement whereas seven eyes had improvement in vision. Four eyes underwent exenteration. All nine patients with limited orbital disease had good improvement with fewer injections (median = 4). None of the patients undergoing TRAMB had an intracranial extension of disease. Moreover, 8.88% (4/45) of the eyes had post-TRAMB transient inflammation which resolved without any intervention. Finally, 3/41 of the patients died. Conclusions TRAMB can be considered as an useful therapeutic adjunct in managing ROCM. Further, it can halt the progression of the disease while awaiting definitive surgical intervention.
RESUMO
Purpose: To determine the status of proangiogenic factors in the tear fluid of preterm infants with and without retinopathy of prematurity (ROP). Methods: Preterm infants (n = 36) undergoing routine ROP screening included in the prospective study were categorized as No-ROP (n = 13, no ROP at any visits), ROP (if ROP was present at first visit; n = 18), or No-ROP to ROP (no disease at first visit, but developed ROP subsequently; n = 5). Infants with ROP were also grouped as progressing (n = 7) and regressing (n = 16) based on ROP evolution between the first and subsequent visits. Schirmer's strips were used to collect tear fluid and proangiogenic factors (VEGF, angiogenin, soluble vascular cell adhesion molecule, and fractalkine) levels (in picograms per milliliter) in tear fluid were measured by multiplex ELISA. Results: Lower levels of VEGF (135 ± 69; mean ± standard deviation) and higher levels of angiogenin (6568 ± 4975) were observed in infants with ROP compared with infants without ROP (172.5 ± 54.0; 4139 ± 3909) at the first visit. Significantly lower levels of VEGF were observed in the No-ROP to ROP group compared with the No-ROP and ROP groups. The VEGF and angiogenin levels at the first visit were significantly lower in infants with ROP with progressing disease. Angiogenin levels negatively correlated with birth weight and gestational age in ROP. The area under the curve (AUC) and odds ratio (OR) analysis demonstrated that angiogenin/birth weight (AUC = 0.776; OR, 8.6); angiogenin/gestational age (AUC = 0.706; OR, 7.3) and Angiogenin/VEGF (AUC = 0.806; OR, 14.3) ratios were able to differentiated preterm infants with and without ROP. Conclusions: The association between angiogenin and ROP suggests its possible role in ROP. The ratio of angiogenin level with birth weight, gestational age, and/or VEGF could serve as a potential noninvasive screening biomarker for ROP.

PURPOSE: To report a case of successful closure of traumatic macular hole after treatment with intraocular steroids in a nonvitrectomized eye. METHODS: Retrospective observational case report. CASE DESCRIPTION: A 34-year-old man developed a full-thickness macular hole and submacular bleed after injury with firecracker in the left eye. Visual acuity in the left eye was counting fingers close to face. Intraocular gas, 0.3 cc of 100% SF6, was injected for displacement of submacular bleed. At 2 months after presentation, macular hole persisted with signs of intraocular inflammation. A trial of intraocular triamcinolone injection (2 mg in 0.05 ml) was given, which resulted in complete closure of macular hole and improvement in visual acuity to 6/36 and thereby avoiding the need for ocular surgery. CONCLUSION: Ocular steroids could play an important role in successful closure of persisting macular holes in a setting of blunt trauma, especially in a background of uveitis.

PURPOSE: To report a case of successful closure of macular hole after surgery in a patient with choroidal coloboma. METHODS: Interventional case report. CASE DESCRIPTION: A 17-year-old boy developed a full-thickness macular hole at the edge of an inferior choroidal coloboma in the right eye. Visual acuity in the right eye was 20/200. Surgical management with 25-G pars plana vitrectomy, internal limiting membrane peeling, and silicone oil tamponade was performed. At 6 weeks after surgery, the macular hole closed with Type 1 closure. After silicone oil removal, the vision in the right eye improved to 20/60. CONCLUSION: Macular hole in the presence of choroidal coloboma is quite uncommon. With better understanding of the etiopathogenesis of macular hole formation and advances in vitreoretinal surgery, it is safe and useful in attempting surgery in these patients.

Purpose: To study the utility and predictive ability of newer macular hole (MH) indices for closure following surgery. Methods: In this retrospective study, pre- and post-operative optical coherence tomography images of 49 eyes with idiopathic full-thickness MH were reviewed and analysed. Various quantitative parameters of MH like maximum outer diameter (OD), minimum diameter between edges, height, nasal and temporal arm lengths, macular hole angle were noted. Indices including hole form factor, Macular Hole Index, (MHI), Diameter Hole Index (DHI) and Tractional Hole Index (THI) were calculated. Newer area indices like macular hole area index (MAI), cystoid space area index (MCSAI) and tissue area index (MTAI) were calculated using Image J (Ver. 1.51). Receiver operating characteristic (ROC) curves and cut-off values were derived for indices predicting type 1 or type 2 closure. Stepwise regression analysis and binary logistic regression analysis were carried out to predict the chances of hole closure. Results: ROC curve analysis showed indices like MHI, THI and MCSAI were capable of successfully predicting type 1 closure while OD, DHI and MAI predicted type 2 closure. On stepwise regression analysis, MAI was identified as the most important index in predicting the type of hole closure. Using the binary logistic regression analysis, the predictive ability of the model to identify success or failure following MH surgery was 89.7% and 80% respectively. Conclusion: MAI measurement could be used as a single important index in predicting hole closure in idiopathic MH. Further research is required to study this area index in detail.
