Polypoidal choroidal vasculopathy as a disease is yet to be comprehended completely. The clinical features consisting of huge serosanguineous retinal pigment epithelial and neurosensory layer detachments, although unique may closely mimick neovascular age-related macular degeneration and other counterparts. The investigative modalities starting from indocyanine angiography to optical coherence tomography angiography provide diagnostic challenges. The management strategies based on the available therapies are plenty and not vivid. A detailed review with clarifying images has been compiled with an aim to help the readers in getting a better understanding of the disease.

Purpose:To compare clinical outcomes of patients undergoing macular hole surgery with heads-up three-dimensional (3D) viewing system and conventional microscope.Methods:In all, 50 eyes of 50 patients with stage 3 or 4 macular hole were randomized and macular hole surgery [inverted internal limiting membrane (ILM) flap technique] was performed in 25 eyes using 3D viewing system and 25 eyes using conventional microscope. All surgeries were performed by a single surgeon. Patients were followed up for a period of 3 months. Logarithm of the minimum angle of resolution (logMAR) visual acuity, macular hole index, intraoperative parameters such as total surgical time, total ILM peel time, number of flap initiations, duration of Brilliant Blue G dye exposure, illumination intensity, postoperative logMAR visual acuity, and macular hole closure rates were recorded and compared between the two groups.Results:The mean age was 67.92 ± 7.95 and 67.96 ± 4.78 years in both groups, respectively (P = 0.98). Gender (P = 0.38) and right versus left eye (P = 0.39) were also comparable. Preoperative and postoperative best-corrected visual acuity (P = 0.86, 0.92), macular hole index (P = 0.96), total surgical time (P = 0.56), total ILM peel time (P = 0.49), number of flap initiations (P = 0.11), and macular hole closure rates (P = 0.61) were not statistically significant when compared between the two groups. Illumination intensity of microscope (100% vs 45%) and endoillumination (40% vs 13%) were significantly less in the 3D viewing system.Conclusion:The clinical outcomes of macular hole surgery using 3D viewing system are not inferior to that of conventional microscopes, and it has the added advantages of better ergonomics, reduced phototoxicity, peripheral visualization, magnification, and less asthenopia, and it serves as a good educational tool.

Purpose: To compare the outcomes of vitreoretinal surgery in patients with primary and recurrent rhegmatogenous retinal detachment (RRD) with proliferative vitreoretinopathy (PVR) on 3 dimensional digitally assisted visualization system (3D-DAVS) and conventional analogue microscope (CAM). Methods: 68 patients with primary (50) and recurrent (18) RRD with PVR > C1 were included. One group underwent surgery on 3D-DAVS while the other on CAM. The parameters studied included detachment rate, best-corrected visual acuity (BCVA), duration of surgery, mean endo-illumination levels of 23 G (Gauge) micro incision vitrectomy system (MIVS) and microscope and satisfaction of surgeon and observers based on a framed questionnaire. The mean duration of follow up was three months. Results: 68 eyes of 68 patients with median age 52.5 (range 18–68) years were included. 50 had primary RRD and 18 had recurrent RRD. Detachment rate at the end of three months was comparable in both groups of primary ( P > 0.99) and recurrent ( P = 0.21) RRD. Mean duration of surgery in minutes for 3D DAVS and CAM group was 61.8 (±22.07) and 58.04 (±12.33), respectively, in primary RRD and 37.22 (±10.27) and 36.55 (±5.92), respectively, in recurrent RRD group. Mean endo-illumination in 3D DAVS (14.5%) group was half of that in CAM (34.17%) group. Surgeon and observer satisfaction scores were significantly higher for 3D DAVS group. Conclusion: 3D DAVS is a safe and effective modality or performing VR surgery in RRD with PVR. 3D DAVS allows lower endo-illumination levels provides superior surgeon ergonomics and offers better learning opportunities to the trainees.

Objective To determine the demographic profile, clinical features and surgical outcomes of giant retinal tear (GRT) related retinal detachments (RD) in children. Methods In this retrospective study, medical records of children aged 14 years and below, who underwent surgery for RD at our centre in the last 5 years were reviewed. Among these, we selected medical records of children with RDs with GRT, and examined the coloured retinal drawings, ultrawidefield photographs and/or surgical videos. Results Out of 1536 medical records, 91 eyes of 87 children (5.6% of all RDs) were included. Mean age was 10.21 ± 3.08 years with male:female ratio of 8.6:1. The most common aetiologies for GRTs were high myopia (28 cases-32.18%) and trauma (25 cases-28.73%). Bilateral RD were possibly present in 29/87 (33.3%) cases. Six months follow up data was available for 82/91 eyes. Overall retinal re-attachment was achieved in 52/82 (63.41%) eyes; in 33/82 (40.24%) eyes retinal attachment could be achieved by a single surgery.

Objectives: To study the clinical features, optical coherence tomography (OCT) findings, treatment options and follow-up outcomes of post-fever retinitis (PFR). Subjects: A total of 19 eyes of 13 patients, diagnosed with PFR (retinitis following febrile episode) over 2 years were retrospectively studied. Methods: Documented history, baseline clinical features and systemic investigations performed for PFR were reviewed. Fundus findings, foveal architecture on swept-source OCT, the treatment options and the follow-up outcomes including best-corrected visual acuity (BCVA) and central foveal thickness (CFT) were reviewed and analyzed. Results: Common fundus findings included whitish retinitis lesions (100%), macular star (95%, 18eyes), retinal flame-shaped hemorrhages (63%, 12 eyes), inflammatory retinal vessels (30%, 6 eyes), vitreous hemorrhage (one eye) and OCT findings included neuro-sensory detachment (79%, 15 eyes), intraretinal white dots (89.5%,17 eyes). The baseline median log MAR BCVA and CFT were 1.30 (interquartile range (IQR):0.8–1.8) and 423 microns (IQR:182–555). Overall, nine patients (12 eyes) received a combination of oral doxycycline and oral steroids and four patients (7 eyes) received a combination of oral doxycycline, oral steroid and intravitreal anti-vascular endothelial growth factor (IVA). Significant improvement was evident at 8 weeks in median BCVA (0.50, IQR: 0.3–0.8, p < 0.05) and median CFT (223 micron, IQR: 170–256, p < 0.05) though only 26% (5 eyes) attained BCVA > = 6/12. Conclusion: Our study puts forth certain characteristic fundus and OCT features of PFR. A combination of oral doxycycline and oral steroids as a treatment option showed improvement in BCVA and CFT. Additional IVA helps in faster visual recovery in patients presenting with severe macular edema at onset.
