Universal slit-lamp–mounted mobile adapter with 20 D lens for fundus photography: “Litter to glitter”

Fundus photography is an arduous task as it involves using 90 D in one hand and a smartphone attached on an eyepiece of a slit-lamp biomicroscope in the other hand. Similarly, with a 20 D lens, the filming distance is adjusted by moving the lens or mobile forward or backward, which makes it difficult to adjust and focus the image in busy ophthalmology outpatient departments (OPDs). Moreover, fundus camera costs thousands of dollars. Authors describe a novel technique of performing fundus photography with a 20 D lens and a universal slit-lamp–mounted mobile adapter made from trash. By the use of this simple, yet frugal innovation, primary care physicians or ophthalmologists without a fundus camera can easily snap a fundus photo and subject it to digital analysis by retina specialists across the world. This will help in simultaneous ocular examination and fundus photos taken via mounted 20 D on a slit lamp itself and also reduce the need for unnecessary retina referrals to tertiary eye care centers.

Smartphone co-aided cobalt blue anterior segment with intraocular lens photography

In this report, we have utilized a smartphone-based innovative tool named anterior segment photography with an intraocular lens (ASPI) with a cobalt blue filter on the smartphone flash for photographing fluorescein-stained corneas. An intraocular lens along with a cobalt blue filter was attached to the smartphone camera to achieve this purpose. The filter could block out all wavelengths of light except the blue wavelength (450–490 nm) emerging from the smartphone camera. A pilot study was conducted on 27 eyes of 25 patients where images of various corneal pathologies were obtained using ASPI blue light imaging. The images were clear and highly magnified and could be used for documentation, teleconsultation for expert opinion, education, and monitoring of disease progression. ASPI-aided blue light imaging could be easily fabricated and is a frugal inexpensive device, which is used by different ophthalmic personnel to obtain fluorescein-stained corneal images.

The Gimbalscope – A novel smartphone-assisted retinoscopy technique

The authors describe a novel technique of performing retinoscopy assisted with a smartphone (gimbalscope). We found this technique of digital retinoscopy to be useful for demonstrating and documenting retinoscopic reflexes and in addition as an easy teaching tool. This technical report explains the assembly of our smartphone-assisted retinoscope and provides examples of the range of normal and abnormal reflexes that can be captured.

Potpourri of retinopathies in rare eye disease – A case series

This case series describes the ocular and retinal manifestations of rare eye diseases in systemic syndromes. This observational case series consists of five patients with varied ophthalmic manifestations and documentation of imaging in rare pediatric and adult retinopathies. Two patients had Kearns Sayre syndrome (KSS) based on the classical triad of external ophthalmoplegia, pigmentary retinopathy, and onset before 20 years of age. In one patient of KSS, the mitochondrial retinopathy was seen in an asymmetric pattern, and the second patient presented with KSS after being mis-diagnosed as myasthenia gravis elsewhere. A case of Senior Loken syndrome in pediatric age is described in this series with varied ophthalmic manifestations ranging from retinitis pigmentosa to orbital abscess. This series also enlightens features of Hallervorden Spatz syndrome presenting with bull’s eye maculopathy and a case of spino-cerebellar ataxia type 7 presenting with pigmentary retinopathy.

PHACOSIT: A sitting phacoemulsification technique for patients unable to lie down flat during cataract surgery

Phacoemulsification is routinely performed with the patient lying supine on the surgical table with his or her head flat and facing the overhead microscope. This routine technique can be a challenge in medical conditions such as kyphosis, scoliosis, orthopnea, Meniere抯 disease, and CNS abnormality. Some cardiovascular and respiratory conditions make the patients breathless when they lie down, whereas other neurological and spinal problem patients are also equally uncomfortable. The only reasonable solution to conduct surgery on a patient who cannot lie down flat on the operating table is to position them face to face in a sitting position. We describe an innovative phacoemulsification technique in a sitting position called 損hacosit� in an 80?year?old wheelchair?bound female patient who was denied cataract surgery by other eye surgeons owing to her medical condition.

Slit-lamp based intraocular lens microscope - A novel technique of rapid office-based microscopy

The emergence of smartphone?based imaging devices has been a boon in the field of ophthalmology, especially in obtaining high?quality ocular images. They can be specialized and utilized for imaging?specific regions of the eye. Among the multitude of applications of smartphone?based imaging, one of the upcoming major use is to image the microbiological world. Previous few reports have described attaching magnifying lenses of various types to the smartphone camera and transforming it into a microscope for imaging fungal hyphae and ocular surface parasites. We describe a novel technique of attaching the smartphone?based intraocular lens microscope (IOLSCOPE) to the slit lamp, thereby utilizing the slit lamp joystick for moving the smartphone over the concerned slide specimen to make it steady and obtain images of high resolution. This innovative do?it?yourself novel modification is especially useful in peripheral centers, vision centers, and local clinics for immediate screening and identification of microbial pathogens such as fungi and ocular surface parasites.
