Outcomes and complications of evisceration with primary implant: an electronic medical record driven analytics of 1800 cases.

PURPOSE: To describe the surgical outcomes and implant complications in 1,800 patients undergoing evisceration with primary implant. METHODS: An Electronic Medical Record-driven analysis of 1,800 patients undergoing evisceration with primary implant between 2013 and 2019. Implant sizing was performed intra-operatively to place the largest implant without tension on the wound closure. Outcome measures included implant complications, prosthesis measurements, and incidence of a good aesthetic outcome. Good outcome was defined as <2 mm enophthalmos and grade 1 or less superior sulcus deformity with a custom ocular prosthesis. RESULTS: Eighteen hundred eyes of 1800 patients were included. The mean age at surgery was 36 ± 21 years (median 32 years). Implants used were poly(methyl methacrylate) (PMMA) in 1737 (97%) and porous polyethylene in 63 (3%) patients. Two-petal sclerotomy was performed in 1512 (88%) and four-petal sclerotomy in 165 (10%) patients. The mean diameter of the implant used was 19.35 ± 1.18 mm (median 20, range 10-22 mm). The implant extrusion rate was 3% (56) and implant displacement was seen in none. The mean prosthesis volume and thickness were 2.22 ± 0.67 ml (median 2, range 1-6.5 ml) and 6 ± 1 mm (median 6, range 2-9 mm). The mean difference in prosthesis projection on Hertel's exophthalmometer was 0.28 ± 1 mm (median 0, range 0-1 mm). Good outcome was observed in 93%. The mean follow-up period was 351 ± 386 days (median 194). CONCLUSION: Evisceration with empirically selected primary orbital implant placement is associated with minimal implant complications and gives a good aesthetic outcome in 93% of the patients.

Retinal vascularity, nerve fiber, and ganglion cell layer thickness in thyroid eye disease on optical coherence tomography angiography.

PURPOSE: To compare the retinal vascularity, peripapillary vascularity, nerve fiber layer thickness and ganglion cell layer thickness between active, inactive thyroid eye disease (TED) and healthy eyes. METHODS: Retrospective comparative cross-sectional cohort study. Patients with TED, active and inactive on the VISA score, and healthy eyes were included. All patients underwent optical coherence tomography angiography with detailed demographic and clinical data capture. Using automated software, retinal and peripapillary vascularity index, nerve fiber layer thickness, and ganglion cell layer thickness were calculated and were compared between the groups. RESULTS: Twenty-four eyes with active TED, 102 eyes with inactive TED and 52 healthy eyes were included. Independent sample t test was used to compare parametric data and Mann-Whitney test to compare non-parametric data. The age and gender were comparable across groups. The peripapillary vascularity index (26.82 ± 4.13 versus 34.92 ± 5.08, p = .002) and the macular vascularity index (20.32 ± 2.5 versus 31.21 ± 3.89, p < .0001) were reduced in active TED eyes versus inactive eyes. Macular vascularity index was comparable in the inactive versus the healthy eyes. The RNFL thickness was increased in the active TED eyes versus the inactive eyes (45.11 ± 18.3 versus 35.55 ± 7, p = .03) and active versus healthy eyes (45.11 ± 18.3 versus 36.28 ± 7.89, p = .03). Ganglion cell layer thickness between all three groups was comparable. CONCLUSION: Decrease in peripapillary and macular vascular density and increase in RNFL thickness are seen in active TED compared to inactive TED and healthy eyes. In disease inactivity, these parameters are comparable to healthy eyes.

Ocular surface squamous neoplasia in India: a study of 438 patients.

PURPOSE: To describe the clinical features, histopathology, treatment, and outcomes of patients with ocular surface squamous neoplasia (OSSN) presenting to a referral centre in India. METHODS: Retrospective interventional study. RESULTS: Of 438 patients, the mean age at presentation was 49 years. Human immunodeficiency virus infection was noted in 72 (16%), xeroderma pigmentosum in 22 (5%), hepatitis B virus infection in 14 (3%), and systemic cancer in 8 (2%) patients. Tumor pigmentation was noted in 243 (54%) tumors with a mean percentage of tumor pigmentation of 44% (median, 40%; range, 1 to 100%). Intraocular tumor extension was noted in 12 (3%), and orbital tumor extension in 16 (4%) eyes. Of the 381 treated lesions, excisional biopsy (n = 247; 65%) was the most common treatment modality. Of the 311 lesions with histopathology diagnosis of OSSN, invasive squamous cell carcinoma (n = 92; 30%) was the most common. Over a mean follow-up period of 11 months (median, 5 months; range, 1 to 108 months) in 368 patients, tumor recurrence was noted in 16 (4%) eyes, globe salvage was achieved in 341 (90%) eyes, vision salvage in 338 (89%) eyes, regional lymph node metastasis occurred in 9 (2%), and metastasis-related death in 9 (2%) patients. CONCLUSION: Pigmented OSSN is common in Asian Indian population. Appropriate management of OSSN is associated with good vision, globe, and life salvage rates in India.

Koebner Phenomenon Triggered by External Dacryocystorhinostomy Scar in a Patient With Psoriasis: A Case Report and Literature Review.

Koebner phenomenon is the development of isomorphic pathologic lesions on a wound of a patient with preexisting cutaneous disease, most commonly psoriasis. An elderly male with palmoplantar psoriasis developed periocular psoriasis in the form of blepharitis and conjunctivitis following an external dacryocystorhinostomy as a manifestation of Koebner phenomenon. Immediate diagnosis and treatment with topical steroids led to complete recovery. Thus, the authors report the first case of Koebner phenomenon in ophthalmic literature, with a review of previously published postsurgical cases of Koebnerization in psoriasis patients. All surgeons should be aware of its existence and warn susceptible patients regarding its occurrence.

Dacryoendoscopy-guided transcanalicular intralesional interferon alpha 2b for canalicular squamous papillomas.

Canalicular papillomatosis is a rare disorder characterized by a mass lesion arising from the epithelium as a stalk from one of the canalicular walls. Traditionally, they have been treated with an open canaliculotomy and excision biopsy with or without additional cryotherapy. A patient with upper canalicular squamous papillomas treated with dacryoendoscopy-guided transcanalicular intralesional and topical interferon alpha 2b is presented, and the ineffectiveness of interferons in this case is discussed.

Primary Nonendoscopic Endonasal Versus Delayed External Dacryocystorhinostomy in Acute Dacryocystitis.

PURPOSE: Conventional treatment for acute dacryocystitis consists of medical management followed by elective delayed external dacryocystorhinostomy (EXT-DCR). The purpose of this study was to compare the outcome after primary nonendoscopic endonasal dacryocystorhinostomy (NEN-DCR) versus conventional treatment in acute dacryocystitis. METHODS: Retrospective chart analysis of all consecutive patients of acute dacryocystitis presenting between 2011 and 2015 was performed. Group A had patients who underwent primary NEN-DCR within 2 weeks of presentation. Group B comprised age- and gender-matched patients who received conventional treatment. RESULTS: Forty-six patients were included with 23 patients in each group. Mean age (45.2 ± 14.7 vs. 47.5 ± 14 years) and gender distribution (women 17/23 in group A vs. 15/23 in group B) in both groups were comparable. Mean duration from presentation to surgery was 7.82 ± 4.65 days for group A versus 27.3 ± 12 days for group B (p = 0.00001, independent T test). Mean time for complete resolution of symptoms was 21.4 ± 6 days for group A versus 38.69 ± 15.8 for group B (p = 0.000014, independent T test). Mitomycin-C usage (0.04%; 17 vs. 14) and mean follow up of both groups (6.4 vs. 5.7 months) were comparable. While functional success was similar (20/23) in both, anatomical success was seen in 22/23 and 21/23 in groups A and B, respectively. Complications included disfiguring scar in 4, recurrent acute dacryocystitis in 3, and punctal ectropion in one patient in the EXT-DCR group. CONCLUSIONS: Primary NEN-DCR leads to faster resolution facilitating earlier rehabilitation with comparable anatomical and functional outcomes compared with conventional delayed EXT-DCR in acute dacryocystitis.

Ophthalmic Artery Occlusion Following Transconjunctival Orbitotomy.

Postoperative blindness after orbital surgery is an extremely rare and a disastrous complication. Ophthalmic artery occlusion as a cause of such unexpected vision loss has not been documented in literature. The authors report a case of a middle aged man who developed sudden vision loss due to ophthalmic artery occlusion following transconjunctival excision of orbital schwanomma. The possible mechanisms contributing to the loss of vision are discussed and preventive strategies are suggested to reduce the incidence of this complication.

Comparative Evaluation of the Ostium After External and Nonendoscopic Endonasal Dacryocystorhinostomy Using Image Processing (Matlabs and Image J) Softwares.

PURPOSE: The purpose of this study was to compare the characteristics of the ostium after external dacryocystorhinostomy and nonendoscopic endonasal dacryocystorhinostomy (NEN-DCR). METHODS: This cross-sectional study included patients who underwent a successful external dacryocystorhinostomy or NEN-DCR and had ≥1 month follow up. Pictures of the ostium were captured with a nasal endoscope (4 mm, 30°) after inserting a lacrimal probe premarked at 2 mm. Image analyses were performed using Image J and Contour softwares. RESULTS: Of the 113 patients included, external dacryocystorhinostomy group had 53 patients and NEN-DCR group had 60 patients. The mean age of patients in the NEN-DCR group (38 years) was significantly (p < 0.05) lower than the external dacryocystorhinostomy group (50 years). There was no statistically significant difference (2 sample t test, p > 0.05) in mean follow up (6 vs. 4 months), maximum diameter of ostium (8 vs. 7 mm), perpendicular drawn to it (4 vs. 4 mm), area of ostium (43 vs. 36 mm), and the minimum distance between common internal punctum and edge of the ostium (1 vs. 1 mm) between the external and NEN-DCR groups. CONCLUSIONS: Image processing softwares offer simple and objective method to measure the ostium. While ostia are comparable in size, their relative position differs with posteriorly placed ostia in external compared with inferior in NEN-DCR.

Canalicular lacerations: Factors predicting outcome at a tertiary eye care centre.

To determine the factors predictive of outcome in canalicular laceration repair at a tertiary eye care centre. A retrospective review of the medical records of all primary canalicular laceration repairs managed at a tertiary eye care centre between the years 2006 and 2014 was done. Thirty-nine patients were included and majority were male (79.5%) with a mean age of 30.05 + 16.2 years (range 2-65). Most (n = 34) had monocanalicular laceration and 5 had bicanalicular laceration. All surgeries were done in the operating room setting. Overall patency by irrigation was seen in 74.4% at a median follow-up of 19.89 weeks (range 21-910). Anatomical outcome was different among the stents and best after Mini-Monoka monocanalicular stent (17/19; 89.5%) followed by bicanalicular annular stents (n = 6; 60%) and 20G Silicone rod (8/14, 57%). The factors predictive of poor outcome were related to the mode of injury [road traffic accidents; Hazard ratio (HR)19.57; p = 0.048] and the type of stent [20G silicone rod (HR 35.7; C.I 3.04 - 419.14; p = 0.004)] by multivariate analysis. Skill of the surgeon was critical as the outcome for fellows-in-training showed a trend towards failure (HR 6.66, p = 0.07). Complications included stent extrusion (n = 28.2%), punctal granuloma (n = 5.1%) and stent exposure (n = 2.5%). The mode of injury - road traffic accidents and type of stent - 20 G silicone rod were risk factors predictive of poorer outcome after canalicular laceration repair. Individual skill of operating surgeon may be a critical factor suggesting a review of training protocols.

Bacteremia Following Nasolacrimal Duct Probing: Is There a Role of Preoperative Antibiotic Prophylaxis?

AIM: To study the incidence of nasolacrimal duct probing-induced bacteremia using the metabolic colorimetric sensor technique of blood culture. METHODS: Prospective, interventional study of all consecutive patients who underwent endoscopic-guided probing for congenital nasolacrimal duct obstruction (CNLDO). All patients were operated by a single surgeon (MJA). Blood was drawn under strict aseptic conditions before and after probing. Blood culture was performed using the BacT/ALERT microbial detection system and the protocols were followed as per the manufacturer and Clinical and Laboratory Standard Institute guidelines. Probing induced bacteremia was defined as a negative pre-probing culture and a positive post-probing culture. RESULTS: Thirty-one eyes of 25 consecutive patients with CNLDO who underwent probing were studied. The mean age at probing was 27 months. All patients presented with epiphora and occasional discharge. One patient presented with unilateral dacryocele along with an acute dacryocystitis. All the pre and post-probing cultures were negative except for the one with acute dacryocystitis. The subsequent subcultures and identification by VITEK 2 system revealed the bacteremia to be caused by Haemophilus influenzae. CONCLUSION: Nasolacrimal duct probing does not induce bacteremia in routine CNLDO cases unless there is an associated acute dacryocystitis. Preoperative antibiotic prophylaxis is perhaps not needed for systemically healthy CNLDO patients without an acute dacryocystitis. However, with regards to infantile acute dacryocystitis, further evidence is needed to formulate guidelines on additional preoperative antibiotic prophylaxis other than the routine treatment of infection.

Fugo blade-assisted lens aspiration in a case of intra- and retro-lenticular hemorrhage.

Hemorrhage into the crystalline lens is exceedingly rare but has been described following ocular trauma [1, 2], glaucoma surgery [3-5], laser iridotomy [6], pediatric cataract surgery [7], and also in the absence of an obvious pathology [8]. We describe a case of intra- and retro-lenticular organised bleed which presented 9 years following repair of open globe injury and which was treated using fugo blade-assisted lens aspiration. The fugo blade provided adequate endocoagulation of retrolenticular blood during posterior capsulotomy and prevented undue anterior segment hemorrhage.

Demography, Clinical Settings and Outcomes in Evisceration with Implant: An Electronic Medical Records Driven Analytics of 2071 Cases.

PURPOSE: To describe the demography, clinical settings and outcomes in 2071 patients undergoing evisceration across a multi-tier ophthalmology hospital network and comparison of results with the global scenario of clinical settings for evisceration. METHODS: An analysis of 2071 patients undergoing evisceration and implant between 2013 and 2019. RESULTS: The mean age at surgery was 39 ± 22 years. Children constituted 303(15%) of the cases. The four leading indications for surgery included painful blind eye in 760(37%), phthisis bulbi in 552(27%), staphyloma in 215(10%) and open globe injury in 195(9%) patients. The clinical settings encountered were trauma in 852(41%), ocular infection in 714(34%), glaucoma in 198(10%), post ocular surgery in 146(7%), congenital in 95(5%) and uveitis in 21(1%). Trauma and infection remained the commonest clinical settings in the urban (843,75%), rural (622,77%) and metropolitan (101,71%) areas. Decade wise distribution suggested trauma to be the commonest clinical setting in the first 4 decades and infection in the next 6 decades. The mean follow-up period was 351 ± 386 days (median 194). While trauma remained one of the commonest clinical setting in both the developed and the developing economies, painful blind eye and intractable glaucoma were other common clinical settings in the developed economies and infection was one of the leading clinical setting in the developing economies. CONCLUSION: Most patients undergoing evisceration are young. The commonest indications for surgery include painful blind eye and phthisis bulbi. Trauma and infection remain the commonest clinical settings for evisceration in developed and developing economies.

Ocular Surface Squamous Neoplasia Following Keratoplasty in Xeroderma Pigmentosa: A Series of Seven Cases.

Purpose: To describe the clinical features and management of post-keratoplasty ocular surface squamous neoplasia (pk-OSSN) in patients with xeroderma pigmentosum (XP).Methods: Retrospective case series of seven patients with XP.Results: The mean age at diagnosis of pk-OSSN was 22 years (median, 21 years; range, 12 to 37 years). There were four males and three females. Full-thickness keratoplasty (n = 5) and Descemet stripping endothelial keratoplasty (n = 2) were performed for optical (n = 6) and therapeutic indications (n = 1). None of the patients had evidence of OSSN before or at the time of keratoplasty. The mean interval between keratoplasty and pk-OSSN was 44 months (median, 14 months; range, 3 to 109 months). The tumor epicenter was located at the limbus (n = 4), bulbar conjunctiva (n = 1) or cornea (n = 2). The mean dimension of the lesions was 12 mm (median, 11 mm; range, 6 to 18 mm). Treatment details included conjunctival/corneal tumor excision (n = 6), plaque brachytherapy (n = 3; 1 primary, 2 adjuvant) and extended enucleation (n = 1). One patient had tumor recurrence 18 months after OSSN treatment, which was treated with wide excisional biopsy. All patients are alive and free of disease over a mean follow-up period of 37 months (median, 37 months; range, 4 to 65 months).Conclusion: XP patients undergoing keratoplasty can develop OSSN several months to years after keratoplasty and require close follow-up for the same. Wide excisional biopsy with/without plaque radiotherapy is effective in the management of pk-OSSN.

In humans, zona pellucida glycoprotein-1 binds to spermatozoa and induces acrosomal exocytosis.

BACKGROUND: It has been suggested that the zona pellucida (ZP) may mediate species-specific fertilization. In human the ZP is composed of four glycoproteins: ZP1, ZP2, ZP3 and ZP4. In the present study, the expression profile of ZP1 in human oocytes and ovaries, and its role during fertilization, is presented. METHODS: Human ZP1 (amino acid residues 26-551) was cloned and expressed in both non-glycosylated and glycosylated forms and its ability to bind to the capacitated human spermatozoa and to induce acrosomal exocytosis was studied. Monoclonal antibodies (MAbs), specific for human ZP1 and devoid of reactivity with ZP2, ZP3 and ZP4 were generated and used to localize native ZP1 in oocytes and ovarian tissues. RESULTS: The MAbs generated against ZP1 recognized specifically the zona matrix of secondary and antral follicles, ovulated oocytes, atretic follicles and degenerating intravascular oocytes, but failed to react with the Fallopian tube, endometrium, ectocervix and kidney. Escherichia coli and baculovirus-expressed recombinant human ZP1 revealed bands of approximately 75 and approximately 85 kDa, respectively, in western blot. Lectin binding studies revealed the presence of both N- and O-linked glycosylation in baculovirus-expressed ZP1. Fluorescein isothiocyanate-labelled E. coli- and baculovirus-expressed recombinant ZP1 bound to the anterior head of capacitated spermatozoa, however, only baculovirus-expressed ZP1 induced acrosomal exocytosis in capacitated sperm suggesting the importance of glycosylation in mediating the acrosome reaction. The human ZP1-mediated acrosome reaction involved the activation of both T- and L-type voltage-operated calcium channels, but does not activate the G(i)-coupled receptor pathway. Inhibition of protein kinase A and C significantly also reduced the ZP1-mediated induction of the acrosome reaction. CONCLUSION: These studies revealed for the first time that in humans ZP1, in addition to ZP3 and ZP4, binds to capacitated spermatozoa and induces acrosomal exocytosis.

'ZP domain' of human zona pellucida glycoprotein-1 binds to human spermatozoa and induces acrosomal exocytosis.

BACKGROUND: The human egg coat, zona pellucida (ZP), is composed of four glycoproteins designated as zona pellucida glycoprotein-1 (ZP1), -2 (ZP2), -3 (ZP3) and -4 (ZP4) respectively. The zona proteins possess the archetypal 'ZP domain', a signature domain comprised of approximately 260 amino acid (aa) residues. In the present manuscript, attempts have been made to delineate the functional significance of the 'ZP domain' module of human ZP1, corresponding to 273-551 aa fragment of human ZP1. METHODS: Baculovirus-expressed, nickel-nitrilotriacetic acid affinity chromatography purified 'ZP domain' of human ZP1 was employed to assess its capability to bind and subsequently induce acrosomal exocytosis in capacitated human spermatozoa using tetramethyl rhodamine isothiocyanate conjugated Pisum sativum Agglutinin in absence or presence of various pharmacological inhibitors. Binding characteristics of ZP1 'ZP domain' were assessed employing fluorescein isothiocyanate (FITC) labelled recombinant protein. RESULTS: SDS-PAGE and immunoblot characterization of the purified recombinant protein (both from cell lysate as well as culture supernatant) revealed a doublet ranging from ~35-40 kDa. FITC- labelled 'ZP domain' of ZP1 binds primarily to the acrosomal cap of the capacitated human spermatozoa. A dose dependent increase in acrosomal exocytosis was observed when capacitated sperm were incubated with recombinant 'ZP domain' of human ZP1. The acrosome reaction mediated by recombinant protein was independent of Gi protein-coupled receptor pathway, required extra cellular calcium and involved both T- and L-type voltage operated calcium channels. CONCLUSIONS: Results described in the present study suggest that the 'ZP domain' module of human ZP1 has functional activity and may have a role during fertilization in humans.

Thyroid eye disease survey: An anonymous web-based survey in the Indian subcontinent.

Purpose: To evaluate the current practice patterns in the treatment of thyroid eye disease (TED) in Indian subcontinent through a web-based survey of members of Oculoplastics Association of India (OPAI). Methods: This was an online web-based questionnaire survey disseminated via monkeysurvey.com to all ratified active members of OPAI between May 1, 2016 and June 30, 2016. Questions encompassed the background, training, region, and experience of oculoplastic surgeons along with the management protocol of TED. Results: Of the 435 emails sent to OPAI members, 9 bounced and 180 (42.3%) responded within the study period. A large majority (96%) of respondents were oculoplastic surgeons practicing in India and the remaining practiced within South-East Asia. Two-thirds of respondents were oculoplastic surgeons with less than 10 years of clinical experience; 82% were fellowship trained in Oculoplasty. Almost all (99%) favored a multidisciplinary management of TED. A large majority routinely grade the severity (89%) and activity (87%) of disease before management. While corticosteroid remained the treatment of choice, 54% preferred immune-modulators as the second-line of therapy for recalcitrant TED. Three-quarters did not use orbital radiotherapy as a management modality in active TED owing to concerns over its efficacy and/or safety. Conclusion: The survey gives useful insights to the practice patterns of TED management in Indian subcontinent. Multidisciplinary approach and grading of disease severity and activity were the rule rather than exception among OPAI members. Immune modulation was the preferred steroid-sparing agent in recalcitrant disease. Orbital radiotherapy was an uncommon treatment choice.

Primary nonendoscopic endonasal versus external dacryocystorhinostomy in nasolacrimal duct obstruction in children.

PURPOSE: The aim is to compare the outcome of nonendoscopic endonasal dacryocystorhinostomy (NEN DCR) with external DCR (EXT-DCR) in the treatment of nasolacrimal duct obstruction (NLDO) in children. METHODS: A retrospective, comparative chart analysis of all consecutive children <16 years after EXT-DCR or NEN-DCR between June 2012 and February 2016. RESULTS: Seventy-one children (79 eyes) underwent DCR in the study, of which 37 children (40 eyes) underwent EXT-DCR and 34 (39 eyes) NEN-DCR. Mean age of both groups (8.7 vs. 7.7 years) was comparable. Etiologically, persistent congenital NLDO was the most common indication (50% vs. 72%), followed by acquired and secondary NLDO. Mean duration was shorter for NEN-DCR (47 vs. 37 min; P = 0.0021). Mitomycin C 0.04% was used more often in NEN-DCR (10% vs. 56.41%). Success after primary EXT-DCR was 100% as compared to 75% for primary NEN-DCR at median follow-up of 12 and 16 months respectively. At revision, the main cause of failure was granuloma (60%). After revision, all eyes were symptom-free at a median follow-up of 9.5 months. CONCLUSION: Primary NEN-DCR has a poorer outcome than EXT-DCR in the treatment of NLDO in children and is more likely to need a revision procedure.

Transconjunctival dacryocystorhinostomy: An aesthetic approach.

PURPOSE: To report the anatomical and cosmetic outcome of transconjunctival dacryocystorhinostomy (TDCR) in an Asian Indian population. METHODS: TDCR was initially performed in cadaver eyes followed by patients with primary acquired nasolacrimal duct obstruction (NLDO). This was a prospective noncomparative case series of all consecutive TDCRs performed between April 2013 and June 2015. Outcome measures were anatomical patency, epiphora, presence of diplopia, aesthetic outcome, and health status. RESULTS: A total of 17 (18 eyes) patients with a mean age 43.9 ± 11.8 years (range, 32-75) were included in the study. Eight were males, and one patient underwent TDCR in both eyes. TDCR was successfully performed in 15/18 (82%) eyes under local anesthesia. Procedure converted to transcutaneous external DCR in two and dacryocystectomy in one patient each. Mean duration of surgery was 52.6 (range, 29-110) min. Anatomical patency and relief from epiphora was achieved in all (15/15) eyes after TDCR at a median follow-up of 15.5 months. At final follow-up, objective assessment of the cosmetic outcome graded the surgical scar at the lateral canthus as invisible in all except one and conjunctival fornix as visible only after eyelid eversion in all patients. Disturbance of the medial fat pad was not seen in any patient. A questionnaire-based health status evaluation showed marked improvement in anxiety/depression before and after TDCR with an overall well-being score of 88 on a scale of 0-100 (worst-best) after TDCR. CONCLUSIONS: TDCR offers a promising aesthetic approach in patients with primary acquired NLDO and gives excellent functional and cosmetic outcome.

Nonendoscopic endonasal dacryocystorhinostomy: Outcome in 134 eyes.

AIMS: To evaluate the outcome of nonendoscopic endonasal dacryocystorhinostomy (NEN-DCR) in patients with nasolacrimal duct obstruction (NLDO) in India. METHODS: Retrospective case series of NEN-DCR between July 2012 and October 2014. All patients had follow-up >3 months. Success was defined anatomically as patency on irrigation and functionally as relief from epiphora. STATISTICAL ANALYSIS USED: Fischer's exact test and Chi-square test. RESULTS: A total of 122 patients (134 eyes; 81 female; mean age 37 ± 18 years) were included. Indications were primary acquired NLDO in 92 (68%) eyes of adults (>18 years), NLDO in children (<18 years) in 22 eyes (16%), acute dacryocystitis in 13 eyes, failed prior DCR in six eyes, and secondary acquired NLDO in one eye. Mean duration of surgery was 36 min (range: 16-92). At a median follow-up of 6 months (range: 3-15), 86% eyes had functional success and 85% had anatomical success. Revision NEN-DCR was successful in 13/16 eyes. All patients with acute dacryocystitis were completely symptom-free at final visit. In children, (17/22) 77% achieved functional success after primary NEN-DCR which improved to 100% after one revision. Tube-related epiphora and granuloma in ten eyes resolved after removal. CONCLUSION: NEN-DCR gives good outcome in primary NLDO and is also effective in those with acute dacryocystitis and in children with NLDO. The technique obviates the need for an endoscope and has an acceptable safety profile and thus may be particularly suited for the developing nations.

Acute lymphoblastic leukemia as second primary tumor in a patient with retinoblastoma.

Second primary tumor (SPT) is defined as a second tumor that presents either simultaneously or after the diagnosis of an index tumor. Second primary malignancies are the leading cause of death in patients with heritable retinoblastoma (RB). Acute lymphoblastic leukemia (ALL), as SPT in RB patients, is extremely rare. To the best of our knowledge, only five cases of ALL as SPT in patients with RB has been documented in the literature. Herein, we report a case of a 6-year-old girl with bilateral RB, who developed ALL during the course of treatment of RB. This case highlights the importance of reviewing blood investigations regularly to diagnose leukemia as SPT in RB and also the necessity for proper counseling and lifelong follow-up in these patients.
