A Comparative Analysis of the Efficacy of Ginkgo Biloba and Caroverine in the Management of Idiopathic Tinnitus.

Aim: The sound sensation that is experienced in the ears or brain and is unrelated to any external sources of stimulus is known as tinnitus. Tinnitus Functional Index (TFI) is used to establish the presence of the condition and determine symptom severity, its impact on the patient's quality of life, thus in this study, we aim to compare the efficacy of caroverine and Ginkgo Biloba in the management of idiopathic tinnitus using TFI. Methods: This clinical study was conducted in at a tertiary care hospital in North India, for a duration of one year, among patients with chronic tinnitus. The sample size for this study consisted of 60 patients in each of three groups (caroverine, gingko biloba, and multivitamin). Assessments of TFI and pure-tone audiometry were performed to evaluate the efficacy of the two medications. The information pertaining to the subjects was kept anonymous and confidential. During data analysis, an association was significant for p value < 0.05. Results: The patients in three groups were matched for the age, gender and duration of tinnitus. At 6 months of medication with Ginkgo Biloba, patients experienced a significant (p < 0.0001) decrease of 50.0% in tinnitus of moderate severity, and a complete resolution of severe tinnitus symptoms with a percentage change of -100.0%. Conclusion: In our study, Ginkgo Biloba Group has significantly improved the severity of idiopathic tinnitus. Tinnitus has diverse underlying mechanisms, can be a symptom of various underlying diseases, and is challenging to measure. Further research is warranted to validate and explore these treatment options further.

Optic neuritis in Rosai Dorfman disease.

A 55-year-old man while being evaluated for unexplained weight loss was found to have multiple metabolically active lymph nodes on positron emission tomography-computed tomography (PET-CT) scan, and biopsy from right axillary lymph node demonstrated multiple histiocytes with emperipolesis with S100 positivity, consistent with Rosai-Dorfman disease.

A Large Irritation Fibroma of the Hard Palate: A Rare Clinical Entity.

An irritative fibroma of the oral cavity can be defined as a benign tumor of connective tissue. They usually occur in the oral cavity, with the most common sites being the buccal mucosa and tongue. However, reported cases over the hard palate are few. Irritant or reactive fibromas are brought upon by recurrent, mildly intense stimulation of the oral mucosa. This can be because of repeated tobacco chewing, ill-fitted dentures, intentional or unintentional biting, sharp teeth, and so on. Because, clinically, fibromas resemble the features of other benign or reactive tumors, histological examination is required for the appropriate management of the same. Here, we describe a case of an irritative fibroma of the hard palate in a 61-year-old female. The patient had a history of betel nut and tobacco chewing for 30 years. The patient was evaluated and underwent complete excision for the same. The base of the lesion was cauterized to prevent recurrence.

Impact of weight reduction on structural and functional parameters of the optic nerve in idiopathic intracranial hypertension.

PURPOSE: To evaluate the effect of weight reduction on the structural and functional parameters of the optic nerve in established cases of papilledema in Idiopathic Intracranial Hypertension (IIH). METHODS: A prospective observational study in early and established cases of papilledema in IIH presenting from December 2019 to February 2021. Functional parameters (visual acuity, contrast sensitivity, mean deviation, VER), structural parameters (RNFL, GCL-IPL, and optic disc height), and clinical grading of papilledema were measured at baseline and every 6 weeks for 6 months. All patients underwent medical (oral acetazolamide) and diet therapy. RESULTS: Mean body mass index (BMI) at presentation was 26.32 ± 3.52 kg/m² and the mean change in BMI over 6 months was 1.27 ± 0.50 kg/m². 67% of eyes had papilledema of grades 2-3 at the presentation. At the end of 6 months, 75% of eyes had grade 1 papilledema while 13% showed complete resolution. A reduction of 5.32 ± 3.58 in mean deviation (r = 0.316; p-value 0.01) and gain in VER P100 amplitude of 4.2 ± 2.7 µV (r = 0.40; p-value 0.003) were noted over 6 months with reduction in BMI over 6 months. A statistically significant reduction in optic disc height (ODH) was noticed with BMI reduction over 6 months (p = 0.0007; r = 0.45).A reduction of 1.72 ± 0.90 kg/m² (equivalent to 6.53% weight loss) in BMI was associated with a four-grade change in clinical grading of papilledema. CONCLUSION: Reduction in BMI had a significant impact on both structural and functional parameters of the optic nerve in IIH. The involvement of a well-certified dietician should be an integral part of treatment in IIH.

Evaluation of Peripapillary and Macular Optical Coherence Tomography Angiography Characteristics in Different Stages of Papilledema.

BACKGROUND: Prospective evaluation of optical coherence tomography (OCT) and OCT angiography (OCT-A) characteristics in different stages of papilledema in idiopathic intracranial hypertension (IIH). METHODS: In this prospective, observational study patients of IIH with papilledema were recruited and divided into 3 groups-early/established (Group 1), chronic (Group 2), and atrophic papilledema (Group 3). Peripapillary retinal nerve fiber layer (RNFL) and macular ganglion cell inner plexiform layer (GC-IPL) were recorded on OCT. Peripapillary and macular perfusion was documented at superficial retinal, deep retinal, and choriocapillary level using OCT-A. The investigations were repeated at 3 months. RESULTS: RNFL showed significant thinning in all groups on follow-up with the atrophic group showing maximum thinning ( P = 0.01-Group 3). GC-IPL was significantly reduced in all stages of papilledema at baseline compared with the controls. Thinnest GC-IPL was noted in the atrophic group (52.75 ± 7.44 µm; P = 0.00 in Group 3 vs controls) that showed further deterioration on follow-up. On Image J analysis, significant decrease was noted at various levels in the peripapillary and macular perfusion at baseline especially in the atrophic group which showed further deterioration noted on follow-up. The final visual acuity showed a statistically significant weak negative correlation with baseline RNFL (r = -0.306) and GC-IPL (r = -0.384) and moderately negative correlation with baseline superficial peripapillary retinal perfusion (r = -0.553). A significant negative correlation was seen between increasing grade of papilledema and superficial peripapillary retinal perfusion with both Image J and automated indices (r = -0.46; r = -0.61), respectively. CONCLUSIONS: GC-IPL may help identify early damage in papilledema even in the presence of thicker RNFL. Significant vascular changes can be observed on OCT-A that may help predict the final visual outcome in papilledema due to IIH.

Evaluation of change in objective cyclotorsion after various inferior oblique-weakening procedures.

PURPOSE: To study the effect of four types of inferior oblique-weakening procedures on ocular torsion: inferior oblique recession (IOR), recession and antero-positioning (RAP), anterior transposition as practiced by Elliot and Nankin (EN), and anterior and nasal transposition (ANT). METHODS: The medical records of 72 consecutive patients >10 years of age undergoing inferior oblique weakening for primary or secondary inferior oblique overaction (IOOA) with or without horizontal rectus surgery were reviewed retrospectively. The 106 included eyes were assigned to one of the four groups according to the type of inferior oblique-weakening procedure. The severity of IOOA and the amount of V pattern guided the choice of procedure. IOOA, disk-fovea angle (DFA), and the amount of V pattern were recorded preoperatively. Measurements were repeated postoperatively at 1 week, 4 weeks, and 3 months. Change in the DFA was used to study the change in objective cyclotorsion in all four groups. RESULTS: A significant incyclotorsional shift was seen in all four groups at postoperative 3 months. The mean reduction in excyclotorsion 3 months postoperatively was 3.65° ± 4.84° for IOR, 5.31° ± 4.64° for RAP, 6.10° ± 3.89° for EN, and 16.62° ± 8.72° ANT; it was significantly higher in the ANT group compared with the other three groups. Reduction in DFA was also correlated with preoperative DFA overall, and for all procedures except IOR (P ≤ 0.005). CONCLUSIONS: All four inferior oblique-weakening procedures reduced excyclotorsion; the largest reductions in our study were seen in cases treated using ANT of the inferior oblique.

Antibiotic prophylaxis for cataract surgery - Practice patterns amongst Indian Ophthalmologists.

Purpose: To assess the current trends in use of perioperative antibiotic prophylaxis, especially intracameral antibiotics (ICAB), for cataract surgery in India. Methods: This was an E-survey using a previously validated questionnaire carried out by the All India Ophthalmological Society (AIOS) in August 2022. An E-mail invitation to complete an online 40-point survey was sent to all members of the AIOS using a digital E-mail service (Survey Monkey) and social media platforms. Results: Out of 1804 total respondents, 58% (n = 1022) reported using routine ICAB prophylaxis. Of those using ICAB, 89% (n = 909) reported using it for all cases, whereas the rest used it for specific indications such as post-PC rent (n = 43), one eyed patient (n = 19), and high-risk cases (n = 50). Commercially available moxifloxacin was by far the commonest agent used for ICAB (n = 686, 67%). Eighty respondents (8%) reported noticing occasional toxic reactions and nontoxic corneal edema (n = 64, 6%) with ICAB. Surgeons with >10 years' experience especially practicing in medical colleges used fewer ICAB (OR = 0.52, 95%CI = 0.38 - 0.72, P < 0,001) compared to younger surgeons (<5-year experience) in solo clinics. The commonest reason for nonadoption of IC antibiotics was "unconvinced of the need to use it in my setting" (n = 296, 52% of those who answered this question). Conclusion: IC antibiotic prophylaxis for cataract surgery has significantly increased in India from 40% in 2017 to 58% in 2022. Commercially available moxifloxacin was preferred by the majority users. Intraocular inflammation may occur occasionally and needs safer formulations to avoid this.

Evaluation of the Levels of Low-dose Topical Atropine (0.01%) in Aqueous and Vitreous Humor in Human Eyes.

SIGNIFICANCE: This is the first human study that confirmed penetration of 0.01% topical atropine in aqueous and vitreous humor in live human eyes. This supports the possible mode of action of atropine via posterior ocular structures. This knowledge will help improve the outcomes in myopia management. PURPOSE: The purpose of this study was to evaluate penetration of low-dose atropine 0.01% in aqueous and vitreous humor. METHODS: In this cross-sectional interventional pilot study, 48 cataract cases were divided into four groups (12 each), and 30 epiretinal membrane/macular hole cases were divided into three groups (10 each). One drop of 0.01% atropine was put in the eye to be operated. Aqueous humor samples were taken from patients undergoing cataract surgery at 60 ± 15 minutes in group 1, 120 ± 15 minutes in group 2, 240 ± 15 minutes in group 3, and 360 ± 15 minutes in group 4. Vitreous humor samples were taken from patients undergoing vitreoretinal surgery for epiretinal membrane/macular hole at 120 ± 15 minutes in group 1, 240 ± 15 minutes in group 2, and 360 ± 15 minutes in group 3. The assay of atropine was performed using liquid chromatography-mass spectrometry. RESULTS: Median concentrations of atropine in aqueous samples were 1.33 ng/mL (min-max, 0.6 to 6.46 ng/mL; interquartile range [IQR], 3.05 ng/mL) at 60 minutes, 2.60 ng/mL (min-max, 0.63 to 4.62 ng/mL; IQR, 1.97 ng/mL) at 120 minutes, 1.615 ng/mL (min-max, 0.1 to 3.74 ng/mL; IQR, 1.62 ng/mL) at 240 minutes, and 1.46 ng/mL (min-max, 0.47 to 2.80 ng/mL; IQR, 1.73 ng/mL) at 360 minutes, and those in vitreous samples were 0.102 ng/mL (min-max, 0 to 0.369 ng/mL; IQR, 0.366 ng/mL) at 120 minutes, 0.1715 ng/mL (min-max, 0 to 0.795 ng/mL; IQR, 0.271 ng/mL) at 240 minutes, and 0.2495 ng/mL (min-max, 0 to 0.569 ng/mL; IQR, 0.402 ng/mL) at 360 minutes, respectively. CONCLUSIONS: Measurable concentration of low-dose topical atropine (0.01%) was noted in aqueous and vitreous humor after instillation of a single drop of low-dose atropine. Muscarinic receptors located in the posterior segment such as the choroid and retina could be the possible site of action of low-dose atropine in myopia.

Rectus muscle pseudo-adherence syndrome.

Purpose: To describe a clinical entity called "rectus muscle pseudo-adherence syndrome" following buckling surgery. Methods: A retrospective data review was undertaken to analyze the clinical profile of strabismus patients who had developed it following buckling surgery. Between 2017 and 2021, a total of 14 patients were identified. The demography, surgical details, and intraoperative challenges were reviewed. Results: The average age of the 14 patients was 21.71 ± 5.23 years. The mean pre-op deviation was 42.35 ± 14.35 prism diopters (PD) of exotropia, and the mean post-op deviation was 8.25 ± 4.88 PD of residual exotropia at 26.16 ± 19.53 months follow-up. Intraoperatively, in the absence of a buckle, the thinned-out rectus adhered to the underlying sclera with much denser adhesions along its margins. When there was a buckle, the rectus muscle adhered to the outer surface of the buckle again, but less densely, with marginal union into the surrounding tenons. In both scenarios, due to the absence of protective muscle coverings, the rectus muscles were naturally adsorbed onto the immediately available surface in the presence of active healing by the tenons. Conclusion: While correcting ocular deviations following buckling surgery, a false sense of an absent, slipped, or thinned-out rectus muscle is very much possible. This is due to active healing of the muscle with the surrounding sclera or the buckle in a single layer of tenons. This is the rectus muscle pseudo-adherence syndrome, where the culprit is the healing process and not the muscle.

Extraocular muscle ductions following nasal transposition of the split lateral rectus muscle.

OBJECTIVE: To quantify changes in ductions following nasal transposition of the split lateral rectus muscle (NTSLR) for treating third nerve palsy. DESIGN: Retrospective cohort study. PARTICIPANTS: A single eye from each patient with third nerve palsy treated with NTSLR with ocular motility measurements. METHODS: Observation of changes in pre- and postoperative ductions. Outcome measures including patient demographic and surgical factors associated with the ability to adduct beyond the midline after NTSLR were evaluated using multivariable logistic regression. RESULTS: A total of 116 patients met the inclusion criteria for this study. The NTSLR significantly decreased abduction (median of 0 limitation [interquartile range (IQR), 0-0] prior to surgery to -4 [IQR, -4 to -3] after NTSLR; p < 0.001), with a corresponding improvement in adduction (median, -5 [IQR, -5 to -4] prior to surgery to -4 [IQR, -4 to -3] after NTSLR; p < 0.001). There was no change in median supraduction or infraduction after NTSLR (p > 0.05). The ability to adduct beyond the midline after NTSLR was demonstrated in 42% of patients. Although not statistically significant, a trend toward a postoperative ability to adduct beyond the midline was seen in patients who had concurrent superior oblique muscle tenotomy (odds ratio [OR] = 5.08; 95% CI, 0.91-40.9) or who were designated with partial rather than complete third nerve palsy (OR = 2.29; 95% CI, 0.82-6.70). CONCLUSIONS: NTSLR improves the horizontal midline positioning of eyes with third nerve palsy. Most eyes lose the ability to abduct, but some regain a modest ability to adduct while vertical ductions remain unchanged.

Stereopsis following surgery in children with congenital and developmental cataracts: A systematic review and meta-analysis.

We estimated the proportion of children with stereopsis following surgery in congenital and developmental cataracts by systematic review and meta-analysis and also considered the factors influencing stereopsis, such as intervention age and presence of strabismus. Stereopsis is directly related to quality of life, and investigating its levels following cataract surgery in children may help decide the right time to intervene, particularly in the context of brain plasticity. We conducted a systematic literature search using Scopus, PubMed, and Web of Science and found 25 case series, 3 cohorts, and 3 clinical trial studies from 1/1/1995 to 31/12/2020. Study-specific proportions of stereopsis from 923 children were pooled using a random-effects model, and stratified analyses were conducted based on intervention age and pre-existing strabismus as a confounder. We appraised the risk of bias using tools published by National Institutes of Health and evaluated publication bias with funnel plots and the Egger test. The pooled proportions of stereopsis based on 8 unilateral and 6 bilateral congenital cataract studies were 0.37 (95% CIs: [0.24, 0.53]) and 0.45 (95% CIs: [0.24,0.68]) when patients with preexisting strabismus were excluded as a confounder. When the intervention age was ≤6 months, proportions in unilateral congenital cataract group significantly increased to 0.52 (95% CIs: [0.37, 0.66]; P = 0.49) compared to 0.26 (95% CIs: [0.14, 0.44]; P = 0.16) otherwise. A similar increase in proportions was found when intervention age ≤4 months. In both unilateral and bilateral congenital cataract groups, proportions increased significantly when the confounder was excluded. Overall, proportions in bilateral congenital cataracts were significantly greater than unilateral cases (irrespective of confounder). Eight unilateral and 5 bilateral developmental cataract studies resulted in pooled proportions of 0.62 (95% CIs: [0.27, 0.88] and 0.82 (95% CIs: [0.4, 0.97]), respectively. Although proportions for bilateral developmental cataracts were greater than unilateral cataracts (irrespective of confounder), results were not statistically significant. Finally, proportions in unilateral developmental cataracts were significantly greater than unilateral congenital cataracts (Z = 7.413, P = 6.173694e-14). We conclude that surgical intervention within first 4-6 months can significantly affect postoperative outcomes in unilateral congenital cataracts. Analysis of existing data does not show a significant effect of intervention age on stereopsis outcomes for developmental cataracts.

Duane syndrome: An overview on the current management.

Duane syndrome is one of the most common restrictive congenital strabismus characterized by variable horizontal duction deficits with globe retraction and shoots on attempted adduction and narrowing of the palpebral aperture. It is now listed as a congenital cranial dysinnervation disorder. The disease is usually unilateral with female preponderance. Basic etiopathogenesis involves dysinnervation of the lateral rectus (LR) due to aplastic/hypoplastic abducens nucleus with a secondary aberrant supply to the LR by the medial rectus (MR) subnucleus of the oculomotor nerve. Diagnosis of the disease is usually clinical. Due to the variable presentation of the disease, surgical management is a challenge and has to be individualized to achieve alignment in the primary gaze, reduction in globe retraction, upshoots and downshoots, and correction of any abnormal head posture. Differential recessions of the lateral and MR muscles are done to correct esotropia or exotropia in the primary gaze. For globe retraction and shoots, Y-split or periosteal fixation of the LR muscles is done depending on the severity.

Understanding the postmortem changes in concentrations of methanol in ocular matrices in rabbits.

Death due to abuse and accidental ingestion of methanol is widely known around the globe. The paper presents the postmortem changes in concentrations of methanol in the vitreous humor, aqueous humor, and ocular tissues in a rabbit model in methanol intoxication. Rabbits were intoxicated with methanol at a dose of 6.3 ml/kg through oral gavage. After 3.5 h of methanol administration, the rabbits were sacrificed. Vitreous humor, aqueous humor, and ocular tissues were collected both, perimortem (immediately) and postmortem (17 h post-death). Whole blood and plasma samples were also collected to explore the correlation between levels of methanol in whole blood/plasma and ocular fluids/ocular tissues if any. All the samples were analyzed by Headspace Gas Chromatography. The analysis revealed a decrease in methanol levels at postmortem for all the matrices, except for retina-choroid than its perimortem value. For retina-choroid, no significant change in methanol levels at postmortem was found.

Novel Inferior Oblique Muscle Y Splitting Procedure to Minimize the Anti-Elevation Syndrome: A Pilot Study.

Purpose: To describe novel Y splitting procedure of inferior oblique muscle to mitigate the anti-elevation syndrome. Methods: A pilot, prospective interventional study was undertaken to assess the effect of inferior oblique muscle Y-splitting in patients with unilateral 3+ or more overaction. To correct primary gaze hypertropia and the excyclotorsion, a Y-splitting procedure was performed (along with routine horizontal muscle surgery as per the deviation) in 14 subjects. The effect of surgery was assessed at baseline and at 6 months post-intervention. Results: The mean age of 14 subjects was 25.14±7.70 years. The mean pre-operative hypertropia, excyclotorsion and inferior oblique muscle over-action was 18.42±3.50 PD, 14.14±2.65 degrees, and +3.21±0.42 respectively. Following surgery, this was reduced to 1.57±1.74 PD of residual hypertropia (a net correction of 16.85±2.31 PD, p = 0.005), 3.85±1.46 degrees of residual excyclotorsion (a net correction of 10.28±1.72 degrees, p < 0.05), and +0.28±0.46 of residual inferior oblique over-action (a net correction ~+3) at the end of 6 months. Amongst fourteen patients, three patients still experienced residual/variable anti-elevation effect, and during the study period none of them experienced any adverse event and none of them required any additional surgeries. Conclusion: While anteriorizing the inferior oblique muscle to correct primary gaze hypertropia and the excyclotorsion, a novel "Y splitting" procedure can be followed to achieve the desired results with mitigated anti-elevation effect.

Ethambutol-induced optic neuropathy: Functional and structural changes in the retina and optic nerve.

BACKGROUD: Ethambutol hydrochloride (EMB) is used in the treatment of tuberculosis and is used as first line modality in combination with other medications. Ethambutol optic neuropathy (EON) is a rare but well-recognised adverse ocular event in patients who receive ethambutol for the treatment of mycobacterial infections and may be potentially devastating with reversible to irreversible changes in visual acuity. KEY FINDINGS: Optical coherence tomography has been used to evaluate the thickness of retinal nerve fibre and ganglion cell layers to look for degenerative changes and early markers. Electrophysiological tests like multifocal electroretinogram, visual evoked potentials and visual fields have been used to understand the functional changes associated with established EON and also whether these can be used to detect subclinical EON and correlate them with the structural changes. In this review, we have summarised evidence published till December 2021 related to evaluation of structural and functional changes in the retina and optic nerve in eyes with EON.

The All India Ophthalmological Society - Academic and Research Committee pan-India diabetic retinopathy project "Fixing the missing link": Prevalence data from Madhya Pradesh and Chhattisgarh.

Purpose: : To determine the prevalence of diabetic retinopathy (DR) and its risk factors among diabetic patients in the states of Madhya Pradesh (MP) and Chhattisgarh (CG). Methods: : Diabetic patients were screened in the treating diabetologist/physician's clinic by a team that included an ophthalmologist, an optometrist, and a counselor. Demographic details, diabetic control, compliance to eye checkup, awareness regarding diabetic blindness, and visual acuity were recorded using a questionnaire. DR was graded both by indirect ophthalmoscopy and fundus photo taken with a portable fundus camera. Results: : In total, 602 subjects were screened across five selected locations of MP and CG. The prevalence of DR was 13.62%. No significant difference with gender was seen. The presence and grade of DR were related to age, diabetic age, and diabetic control. Conclusion: : This study provides the prevalence data for DR among diabetic patients from the states of MP and CG and highlights important barriers to DR screening in our country.

Defining the Clinical Role of Swept-Source Anterior Segment Optical Coherence Tomography in Eyes Undergoing Strabismus Surgery.

Purpose: To describe the clinical role of swept-source anterior segment optical coherence tomography in extraocular muscle imaging in various strabismic conditions. Study Design: Prospective observational study. Participants: A total of 1104 extraocular muscles of 150 subjects were imaged. Normal eyes (640 muscles), eyes undergoing re-operation (240 muscles), paralytic strabismic eyes (16 muscles), non-paralytic strabismic eyes (20 muscles), post-traumatic strabismic eyes (64 muscles), eyes with thyroid disease (64 muscles), and other atypical cases (60 muscles) were imaged. In all cases, up to four recti muscles were evaluated in a given eye depending on the need. Results: The mean age was 38.15 ± 16.25 years. Overall, muscle insertion was identified in over 90% of the subjects. Apart from normal muscles (n = 860, 93.68%), the location was identified in previously operated eyes (n = 54, 90%), in traumatic muscle slippage (n = 2, 11.11%), in ocular coat ectasia (n = 11, 91.66%), in thyroid muscle hypertrophy, in operated scleral fixated intraocular lens with strabismus, and other challenging cases. In all circumstances, clinically useful information was obtained from the anterior 4-14 millimetres of the rectus muscle, which in turn helped in active surgical planning and overall management. Conclusion: The SS-ASOCT with its wider and deeper scanning abilities was able to locate the extraocular muscle insertion in a variety of strabismic conditions. Therefore, this tool can be used in the preoperative periods for optimal surgical planning and management.

Optical coherence tomography features and correlation of functional and structural parameters in patients of idiopathic intracranial hypertension.

Purpose: To determine the correlation between functional parameters and optical coherence tomography (OCT) features in patients of idiopathic intracranial hypertension (IIH). Methods: A prospective observational study in early and established cases of papilledema in IIH presenting from December 2017 to February 2019. Functional parameters (visual acuity, contrast sensitivity, mean deviation, VER, and MfERG) and structural parameters (RNFL, GCL-IPL, and optic disc height) were measured at baseline and every 6 weeks for 6 months. Results: At baseline, average RNFL had a moderate negative correlation with mean deviation (r = -0.45; P = 0.0007) and a positive correlation with logMAR visual acuity (r = 0.18; P = 0.17). On the contrary, baseline GCL and logMAR visual acuity had a negative correlation (r = -0.4, P = 0.02). Optic disc height (ODH) had a negative correlation with visual field mean deviation (r = -0.046; P = 0.0005). At 6 months, ODH and GCL-IPL complex had a statistically significant correlation with functional parameters. However, RNFL values did not show any significant correlation with any of the functional parameters. Baseline GCL-IPL and optic disc height values had a moderate and significant correlation with final functional parameters. However, RNFL did not show any correlation with final functional parameters. Correlation between GCL-IPL thickness at 6 weeks and final functional parameters were stronger than that with baseline GCL values. Conclusion: In the setting of severe papilledema, RNFL can misguide the prognosis. GCL-IPL can be a valuable tool for an objective evaluation of the integrity of the optic nerve in IIH and ODH may be used as an alternative or in combination with GCL-IPL in these cases.
