Technology & Screenings


Our Expertise


At The Retina Clinic London, we understand the importance of comprehensive monitoring for patients undergoing Letrozole therapy. Our Letrozole Retinopathy Screening Service is designed to detect early signs of retinal toxicity associated with Letrozole, ensuring proactive management to safeguard your vision. 

What is Letrozole?

Letrozole is a medication primarily used to treat breast cancer in postmenopausal women by reducing oestrogen levels in the body. However, it can also be prescribed for other conditions requiring oestrogen suppression. 

How can Letrozole affect the retina?

While Letrozole is effective in its intended medical management, it’s not without potential ocular side effects. Letrozole retinopathy can manifest as various changes in the retina, including retinal pigment epithelium (RPE) alterations, retinal haemorrhages, and macular oedema. 

Our Letrozole Retinopathy Screening includes:

Test Description
Best-Corrected Visual Acuity (BCVA) Evaluation of visual acuity with optimal correction to assess central vision.
Colour Vision (Monocularly) Assessment of colour perception in each eye to detect abnormalities.
Amsler Grid Examination of the central visual field for distortions or defects, indicative of macular pathology.
Slit Lamp Biomicroscopy Detailed examination of the anterior and posterior segments of the eye.
Visual Fields Assessment of the visual field to detect any abnormalities
Optos Ultra-Widefield Red/Green/Autofluorescence with Steering Imaging modality to evaluate the retina and to detect any visible change alongside any change in retinal pigment epithelium (RPE).
Heidelberg OCT High-resolution imaging to detect retinal changes.
Full-Field Electroretinography (ERG) Functional testing to assess retinal response.
Microperimetry Testing Assessment of retinal sensitivity to detect reductions in threshold sensitivity.
Adaptive Optics Imaging Advanced imaging technique providing high-resolution images of individual retinal structures.

What makes our screening services special?


Led by Professor Paulo Eduardo Stanga, our medical team comprises highly specialized retinal specialists with extensive experience in managing retinal conditions, including drug-induced retinal toxicity.

Comprehensive Screening Technologies

Utilizing advanced imaging modalities, including some not readily available in most clinics, such as the latest Ultra-widefield Optical Coherence Tomography (OCT), Microperimetry, and Adaptive Optics Imaging, we ensure thorough evaluation and early detection of retinal changes.

Personalised Care

We tailor our screening protocols and treatment plans to meet the specific needs of each patient, ensuring individualized care and support.

Efficient Appointments

We prioritize prompt appointments and efficient follow-up care, ensuring timely screenings and interventions.
