Retro-mode: a newer insight into dry age-related macular degeneration (AMD).

The purpose of this study is to study the role of retro-mode (RM) in early detection and to compare it with other preexisting available modalities on multimodal imaging system in dry AMD. A prospective observational cross-sectional study was done between November 2020 and October 2021 which included 409 eyes of 207 patients. For study purpose, eyes were divided into 3 groups according to the size and number of the drusen, viz, group 1: No AMD, group 2: early AMD and group 3: intermediate AMD which was further divided into 2 subgroups, viz, subgroup A: eyes with drusen size 63-125 μm and subgroup B: eyes with drusen size 125-250 μm.

Vessel density changes in choroid, chorio-capillaries, deep and superficial retinal plexues on OCTA in normal ageing and various stages of age-related macular degeneration.

Purpose: To study vessel density (VD) on optical coherence tomography angiography at choroid, chorio-capillaries (CC) and various retinal levels in normal population and various stages of dry AMD and how these changes progress with increase in severity of the disease.

Methods: Prospective, observational, cross-sectional study was done on 252 eyes of 132 patients (males: 61, females: 71) presenting to tertiary-care centre in Central India between February 2021 and January 2022. For study purpose, eyes were divided into five groups according to the size and number of the drusen, viz, Group 1: No AMD (< 50 years), Group 2: No AMD (> 50 years), Group 3: Early AMD, Group 4: Intermediate AMD and Group 5: Advanced AMD.

Pre-operative optical coherence tomography predictors: Do they hold any relevance in the era of inverted internal limiting membrane flap in large macular holes?

Purpose: To study the relevance of preoperative OCT predictors in large macular holes (MH) treated using the inverted ILM peel technique.

Methods: Prospective study of 95 patients undergoing vitrectomy for large MH between January 2019 and December 2020 was performed by dividing the patients into groups depending on various quantitative parameters and indices of MH such as base diameter (BD), hole form factor (HFF), macular hole index (MHI), diameter hole index (DHI), and tractional hole index (THI) by using parameters such as minimal hole diameter, hole height, nasal and temporal arm lengths. Depending upon the duration of symptoms, patients were divided into three groups: <3 months, 3-6 months, and >6 months.

Aggressive Posterior Retinopathy of Prematurity (APROP): LASER as the Primary Modality of Treatment.

Purpose: To study the success rate of LASER as a primary modality of treatment in aggressive posterior retinopathy of prematurity (APROP) cases.

Methods: This is a prospective case series of 56 eyes of 28 preterm babies (males = 21) with APROP who underwent laser therapy. Babies were divided into groups on the basis of gestational age (GA), birth weight (BW), and postmenstrual age (PMA) at which treatment was performed.

Digitally assisted three-dimensional surgery - Beyond vitreous.

Purpose: The aim of this study was to evaluate the application and safety of three-dimensional (3D) visualization system in varied anterior segment procedures and Scleral Buckle.

Methods: This was a prospective observational study of 313 eyes. Patients undergoing phacoemulsification (PE) with intraocular lens (IOL), trabeculectomies, glaucoma triple procedure (GTP), scleral fixated (SF) IOL, and scleral buckle (SB) were included in the study.

Role of LASERS in stage 4A retinopathy of prematurity (ROP).

To study the anatomical success rate of light amplification by stimulated emission of radiation (LASERS) as first line of management in stage 4A retinopathy of prematurity (ROP). Observational, prospective case series of 14 eyes of 7 babies (males: 3, females: 4) with stage 4A ROP who underwent LASERS for stage 4A between January 2018 and July 2019. Gestation age (GA), birth weight (BW), and post-menstrual age (PMA) at which laser was done were noted in all cases.

Short-term outcomes of intravitreal dexamethasone in relation to biomarkers in diabetic macular edema.

Purpose: The purpose of this study was to determine the effects of dexamethasone implant (0.7 mg) on biomarkers such as hyper-reflective dots, external limiting membrane integrity and disorganization of retinal inner layers in treatment-naïve patients, patients who received less than three anti-vascular endothelial growth factor injections and non-responder cases with diabetic macular edema and its effects on edema and visual acuity.

Methods: This is a prospective study of treatment-naïve patients, patients who received less than three anti-vascular endothelial growth factor injections and non-responder patients with diabetic macular edema, treated with single dexamethasone implant.

Internal limiting membrane peel: Does it change the success rate of primary vitrectomy without belt buckle in rhegmatogenous retinal detachments?

Purpose: To compare the anatomic success of pars plana vitrectomy (PPV) after internal limiting membrane (ILM) peeling at macular area and macular plus peripapillary area versus no peeling in rhegmatogenous retinal detachments (RRD).

Methods: A prospective observational study between July 2014 and March 2017 conducted on 289 eyes of 287 patients with RRD were randomly assigned to three treatment procedures, viz., PPV with no ILM peeling, PPV with macular peeling, and PPV with macular plus peripapillary peeling.

Linear discriminant score for differentiating early primary open angle glaucoma from glaucoma suspects.

Purpose: To determine the diagnostic accuracy of a linear discriminant function (LDF) based on macular ganglion cell complex (GCC), optic nerve head (ONH) and retinal nerve fibre layer (RNFL) for differentiating early primary open-angle glaucoma (POAG) from glaucoma suspects.

Methods: In this cross-sectional study, data from consecutive 127 glaucoma suspects and 74 early POAG eyes were analysed. Each patient underwent detailed ocular examination, standard automated perimetry, GCC and ONH and RNFL analysis.
