Machine learning-based automatic detection of novel coronavirus (COVID-19) disease.

The pandemic was announced by the world health organization coronavirus (COVID-19) universal health dilemma. Any scientific appliance which contributes expeditious detection of coronavirus with a huge recognition rate may be excessively fruitful to doctors. In this environment, innovative automation like deep learning, machine learning, image processing and medical image like chest radiography (CXR), computed tomography (CT) has been refined promising solution contrary to COVID-19.

Novel coronavirus (COVID-19) diagnosis using computer vision and artificial intelligence techniques: a review.

The universal transmission of pandemic COVID-19 (Coronavirus) causes an immediate need to commit in the fight across the whole human population. The emergencies for human health care are limited for this abrupt outbreak and abandoned environment. In this situation, inventive automation like computer vision (machine learning, deep learning, artificial intelligence), medical imaging (computed tomography, X-Ray) has developed an encouraging solution against COVID-19.

Spontaneous Resolution of a Rapidly Formed Dense Cataract Following Nd: YAG Laser Peripheral Iridotomy in a Case of Pigmentary Glaucoma.

A 54-year-old man was referred for a senior opinion. His vision had acutely dropped in his right eye from 6/6 to hand movements following Nd:YAG laser peripheral iridotomy for treatment of pigmentary glaucoma. A dense rosette posterior subcapsular cataract had formed in his right eye rapidly after surgery.

Acute Secondary Optic Neuropathy as a Complication of a Single Episode of Acutely Raised Intraocular Pressure: A Case Series.

Purpose: The purpose of this case series is to report development of acute secondary optic neuropathy due to optic nerve injury associated with single episode of acutely raised intraocular pressure (IOP) of varying etiologies.

Patients And Methods: Retrospective review of a series of 3 consecutive cases diagnosed at University hospitals of Coventry and Warwickshire and review of published literature.

Results: Three cases, respectively, with Posner Schlossman syndrome, acute idiopathic hypertensive anterior uveitis, and primary acute angle-closure initially presented with raised IOPs of 38 to 68 mm Hg.

Secondary Glaucoma due to Iridescent Crystalline Particles Masquerading as Refractory Hypertensive Uveitis in an Eye With Irradiated Iris Melanoma.

Purpose: We report a previously unrecognized mechanism of secondary glaucoma due to iridescent crystalline particles released from an irradiated iris melanoma. It masqueraded as refractory hypertensive uveitis following uncomplicated phacoemulsification.

Materials And Methods: A 58-year-old gentleman had an iris melanoma that underwent successful regression following irradiation with proton beam radiotherapy.

Combined Acute Haemolytic and Secondary Angle Closure Glaucoma following Spontaneous Intraocular Haemorrhages in a Patient on Warfarin.

Background: To report the first described case of combined haemolytic and acute angle closure glaucoma secondary to spontaneous intraocular haemorrhages in a patient on excessive anticoagulation. To the best of our knowledge, this is the first case reported in the literature presenting with raised intraocular pressure due to both mechanisms.

Case Description: A 90-year-old woman presented with acute pain and reduction in vision in the left eye.

Rare case of post-cataract-surgery Prevotella endophthalmitis diagnosed by polymerase chain reaction DNA sequencing.

We report the presentation, diagnosis, and management of endophthalmitis caused by the opportunistic Prevotella species. The case was referred to us following uneventful phacoemulsification and intraocular lens implantation. Accurate identification of this rare cause of endophthalmitis was made using bacterial polymerase chain reaction DNA sequencing.

Extension of retracted glaucoma drainage tube using a 22-gauge intravenous catheter in complex pediatric glaucoma.

Purpose: To describe the use of the readily available, sterile, and economical 22-gauge intravenous catheter (Venflon) as a preferable option for extending the tube of glaucoma drainage devices in cases of tube retraction in complex pediatric cases.

Methods: A report of noncomparative retrospective evaluation of 2 pediatric cases with tube retraction treated with the extension of the tube. The tube of the drainage devices (1 Baerveldt and 1 Molteno) was extended using a segment of a 22-gauge intravenous catheter (Venflon).

Ocular decompression retinopathy after trabeculectomy with mitomycin-C for angle recession glaucoma.

A 45-year-old male presented with intractable glaucoma following 360-degree angle recession after blunt trauma. He underwent an uncomplicated trabeculectomy with mitomycin-C (MMC). Adequate precautions were taken to reduce the chances of sudden lowering of intraocular pressure (IOP).

Potential contamination of the G-probe used for transscleral cyclodiode.

Aim: To present a case where we noted occult contamination of the G-probe used for transscleral cyclodiode and to critically analyze the techniques used for making a G-probe suitable for repeated use.

Materials And Methods: Close microscopic examination of the G-probes used once for transscleral cyclodiode was done and a critical review of the literature on practice of reuse of the G-probe and the techniques used to "cleanse" the probe before reuse was performed.

Results: We noticed microscopic contamination of the G-probe by the tear film fluid in all the probes examined by us.

Optimization of biometry for intraocular lens implantation using the Zeiss IOLMaster.

Purpose: To compare the accuracy of biometry using conventional A-scan ultrasonography and partial coherence interferometry, and to improve the accuracy of biometry by sequential audit of postoperative refractive error.

Methods: The study was performed in three phases. In phase 1, 20 consecutive patients undergoing routine phacoemulsification underwent biometry using both A-scan ultrasonography and the Zeiss IOLMaster (ZIOLM).
